The selected question bank and answers for the 2020 Science Popularity Contest are as follows:
1 What is Entropy? What is the definition of Entropy?
Answer: Entropy is a physical quantity that describes the degree of disorder in a system. The commonly used symbol is S. Its definition can be expressed as: in an isolated system, all physical processes have a random and irreversible property in terms of energetics, that is, the degree of chaos in the system will always increase with time. Thus, the symbol S for the infinity of the value of the entropies means that its absolute value always tends to be positive infinity. The physical properties of entropies could be described by the second law of energetics, which was the law of conservation of energy and the principle of constant entropies.
2 What does the principle of increase in entropies mean? What is the relationship between the principle of the increase of the degree of entropies and the second law of energetics?
Answer: The principle of the increase of the entropies means that the entropies in an isolated system always increase with time. In other words, the increase of the entropies in an isolated system is inevitable. The principle of the increase of the entropies was an important inference of the second law of energetics. It showed that the entropies of an isolated system always tended to increase rather than decrease. The second law of energetics states that in an isolated system, heat cannot flow from a high-temperature object to a low-temperature object, but must flow from a low-temperature object to a high-temperature object.
What is the second law of energetics? What is the basic principle of the second law of energetics?
Answer: The second law of energetics is a law describing the flow of heat in nature. It states that heat cannot flow from a low-temperature object to a high-temperature object, but must flow from a high-temperature object to a low-temperature object. The basic principle of the second law of energetics could be expressed as: All physical processes in an isolated system are energetically random and irreversible. The flow of heat must satisfy the increasing trend of the increment of the entropies, and the flow of heat must also satisfy the increasing trend of the entropies, so the flow of heat must be an inverse entropies flow.
What is quantum mechanics? What are the important features of quantum mechanics compared to classical mechanics?
Answer: Quantum mechanics is a physics theory that describes the behavior of microscopic particles. Compared to classical mechanics, it has the following important features:
(1)The microscopic particles have the properties of particles and waves, and their motion states can be described by probability clouds.
(2)The measurement results of microscopic particles were related to their motion state and could not be simply predicted by the laws of classical physics.
(3)The behavior of microscopic particles is affected by the entanglement of quantum states and quantum superpositions, and their states cannot be determined at the same time.
(4)The basic physical quantities in quantum mechanics, such as energy, momentum, and angular momentum, were scattered and uncertain.
