What are the common physical reactions?
Common physical changes included: 1. ** Change of the Three States of Matter **: - Melting: For example, when wax melts into liquid wax oil, the substance changes from solid to liquid. The shape and state change, and no new substance is formed. - " Boilification: The phenomenon of water turning into steam is the phenomenon of vaporizing. It is the process of changing a substance from a liquid state to a gaseous state. - Sublimation: Like the process of changing solid iodines directly into iodines vapor, substances change from solid to gaseous state. - Solidification: Liquid water freezes, and matter changes from liquid to solid. - Liquefaction: For example, in winter, when indoor water vapor meets a cold lens, it will release heat and liquify into small water droplets that attach to the lens. This is the change of a substance from a gaseous state to a liquid state. - Condensation: Frost in winter is the condensation of water vapor in the air into solid ice crystals, and the substance changes from a gaseous state to a solid state. 2. ** Change in shape **: For example, a matchstick is broken, glass is broken, etc. Only the shape of the substance has changed, and no new substance is produced. 3. Dissolution of substances and evaporating of solution: Salt is dissolved in water, heated and evaporated to obtain solid salt. During this process, the state of the salt changes, and no new substances are produced. 4. ** Other phenomena **: After the water in the kettle is boiled, the " white gas " seen at the spout of the kettle is the small water droplets formed by the condensation of water vapor. There are also phenomena such as tire explosion, balloon explosion, lighting, activated carbon absorption, etc. Read more exciting novels for free
Physical reactions in the game
The body's reaction in the game was varied. In stimulating games, from the perspective of physiological reactions, it was easy to trigger nervousness and anxiety, which would lead to the stimulation of the sympathetic nervous system, which would increase the heart rate and blood pressure. At the same time, visual stimulation would cause reactions such as accelerated heartbeat and constricted blood vessels, which would increase the burden on the heart. Moreover, maintaining the same position for a long time would cause blood circulation to be blocked, causing the heart to increase its burden and discomfort. For example, when playing a 3D game, although the player was still, he was in a dynamic game scene. The eyes saw the moving images and sent signals to the brain, while the inner ear's vestibal receptor could not capture the actual movement of the body. This visual and vestibal system information did not match, causing dizziness, nausea, dizziness, and even vomiting. If the 3D images were switched quickly and the visual stimulation was too complicated, it would cause fear, dizziness, nausea, and vomiting. In addition, people with certain diseases, such as vestibulopathy, vestibulopathy, mental illness, high blood pressure, etc., were more prone to 3D motion sickness. There were also dangerous games such as " Dream of the Great Tang " and " Three Seconds of Death ". Holding one's breath quickly would cause the lungs to be unable to breathe normally. The oxygen intake would decrease, and the carbon dioxide would not be discharged properly. The oxygen content in the blood would decrease, and the carbon dioxide content would increase. It would stimulate the respiratory center to deepen and accelerate breathing. Holding one's breath for too long would cause the respiratory muscles to fatigue or even stop breathing. Chest compressions would compress the heart and reduce the amount of blood returning to the heart, resulting in insufficient blood supply to the brain, causing dizziness, fainting, and even shock. It could also cause permanent damage to the brain and other organs. In severe cases, it could cause the organs of the whole body to stop functioning or even die. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the physical reactions in life?
There were many physical reactions in life. The following were some common examples: 1. ** Phenomena related to mechanics ** - When the battery of the Quartz Clock hung on the wall ran out of power and stopped moving, the second hand would often stop at the "9" position on the dial because the second hand was most hindered by the gravitational moment at the "9" position. - A misshapen mirror, the further away one is from the mirror, the more misshapen it becomes. Because the image in the mirror was formed by the reflection of the silver-plated surface behind the mirror, the uneven silver-plated surface or the uneven thickness of the glass would cause distortion. The farther the person was from the mirror, the more the reflection of the silver-plated surface deviated from the normal position, and the mirror would be more distorted. - Sitting on the ground and traveling 80,000 miles a day, this was because the radius of the earth was about 6370 kilometers. Every time the earth rotated, the distance that the objects on its surface "walked" was about 40,003.6 kilometers, about 80,000 miles. This revealed the relationship between motion and stillness. Movement was absolute, and stillness was relative to the reference object. 2. ** Phenomena related to Optics ** - When one looked up at the starry sky on a clear summer night, the stars kept twinkling. This was because the atmospheric density distribution was unstable, causing the refracted light of the starlight to change with the atmospheric density. - When taking pictures of the TV screen, turn off the camera flash and indoor lights, and the picture would be clearer. This was because the reflected light from the flash and lights on the TV screen would interfere with the transmitted light of the TV screen. - The chopsticks in the water looked shorter because of the refraction of light. The reflection of trees in the water was the reflection of light. The rainbow-colored oil film on the road was the interference of light. The concave lens could be ignited because of the light gathering effect of the concave lens. The spot under the big tree was the phenomenon of small hole imaging. The reflection of people on the road was the phenomenon of straight line transmission of light. The eclipse of the sun and moon was the phenomenon of straight line transmission of light. The rainbow after the rain was the phenomenon of light dispersion. It was the refraction of light that people saw the sunrise earlier than it actually was. A car windshield slanted at a certain angle was a reflection of light. 3. ** Phenomena related to heat ** - There was an air layer in the middle of the double-layer glass. The air was not easy to transfer heat, so the double-layer glass could play the role of heat preservation and insulation. - Meat broth or spicy soup was not easy to cool because the oily layer of vegetable soup covered the surface of the soup, preventing the water from evaporating, so it was not easy to cool. - Before the water boils, due to the air current, the bubbles in the water will rise and vibrate up and down. Most of the bubbles will burst under the pressure of the water, and the sound of the bursting and vibration will resonate with the container, so the sound will be very loud. After the water boils, the temperature will remain the same, and the volume of the bubbles will increase. Under the effect of buoyancy, the bubbles will rise to the surface of the water before bursting. The sound will be relatively small, so there is a saying that "the water will not boil without the sound of boiling water". - In winter, the surface of the lake froze, but there was no ice under the ice. This was the abnormal expansion of water. - Being scalded by steam was more serious than being scalded by water because it liquefied and released heat. 4. ** Phenomena related to electricity ** - Using a heating wire to heat up was the thermal effect of the electric current, and using a microwave to heat up was because the wave had energy. - The magnetic needle around the energized wire would deflect, which was the magnetic effect of the current. The current produced by the rotation of the generator coil was an electromagnetic induction phenomenon. 5. ** Phenomena related to sound ** - As the car drove past, the frequency of the sound gradually decreased. This was the Kepler effect. - Obstacles couldn't stop the transmission of sound, which was the phenomenon of sound wave refraction. Listening to the rails could tell the train was coming earlier because sound traveled faster in iron than in the air. In space, a walkie-talkie was needed because sound transmission required a medium, and space was a vacuum that couldn't transmit sound. 6. ** Other phenomena ** - Clothes turned from wet to dry, clouds turned into rain, glass turned from a whole piece into a small piece, and the fragrance of flowers filled the air. During these processes, the shape and state of the substance changed, but the nature of the substance itself did not change. - The phenomenon of thermal expansion refers to the thermal movement of molecules when an object is subjected to thermal energy, resulting in the expansion of the object's volume. The phenomenon of thermal contraction refers to the reduction of molecular thermal movement when an object is subjected to low temperature, resulting in the condensation of the object's volume. - When two objects move relative to each other, they produce friction. The magnitude of the friction depends on the contact area and the surface toughness. The object is deformed by an external force, and the shape that can be restored after the external force is called elastic. - The suction cup could stick to the wall tightly because of the atmospheric pressure; the hand hurt when using a needle because the pressure was inverse to the surface area when the force was applied; the boat could float on the water because the buoyancy was equal to the gravity of the water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The four types of physical and chemical reactions are
There were four basic types of chemical reactions, namely, chemical combination reaction, decomposition reaction, displacement reaction, and metathesis reaction. Physical reactions did not have such a classification. A chemical reaction is a reaction in which two or more substances form another substance; a decomposition reaction is a reaction in which a substance is decomposed into two or more new substances; a displacement reaction is a reaction in which a simple substance and another compound react to form another new simple substance and compound; a metathesis reaction is a reaction in which two compounds exchange their components to form two other compounds. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Should the physical and chemical battery reactions be balanced?
In physics and chemistry, battery reactions usually needed to be balanced. For the reaction of the primary battery, there are many balancing methods, such as the addition method.(Positive reaction + negative reaction = total reaction): Write down the total reaction and the known reaction of the pole, then make the charge number of the reaction of the pole the same as the total reaction, and finally subtract it to get the reaction formula of the other pole. There was also the alkali-base balancing method. This method required one to first distinguish the acidic and basic properties of the solution. In an acidic solution, hydrogen ions would participate in the reaction, and in an basic solution, hydrogen ions would participate in the reaction. Then, the elements other than hydrogen and oxygen would be balanced and the number of charges would be written. Then, the balance would be further balanced according to the rules of the acidic or basic solution. The balancing of the battery reaction helped to accurately represent the conversion relationship of substances and the transfer of charge during the reaction process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Some people might feel their heart rate slow down and get a lump in their throat.
What are the Common Reactions to Fanfiction?
Positive reactions are very common. People often praise the creativity of the author. They might say things like 'This fanfic has such a unique take on the characters.' Some also get excited and fangirl/fanboy over it, like 'OMG, this is exactly what I wanted to see in a fanfic!' Negative reactions can happen too, like when the story doesn't stay true to the original source material. Then readers might comment 'This doesn't feel like the characters I know at all.'
