Before the exam: I was so nervous that my palms were sweating and my breathing became rapid. I've been thinking about the contents of the exam, wondering what I should do if I accidentally do a wrong question. I didn't know if I could do it well, so I kept reminding myself to calm down. But I really can't calm down. I feel like I'm about to explode. After the exam: I was relieved when the exam was over, but my heart was empty. I didn't know if I had really mastered the contents of the exam. I thought back to my performance in the exam and wondered what I would do if I got a question wrong. I began to worry about my future, wondering if I had the ability to do what I wanted.

The correct way to add water to a lead-acid battery is to use a plastic funnel to slowly pour distilled water or Deionized water into the battery to ensure that the water does not splash on the battery casing or other components, and to avoid pouring water into the battery's charging port or other non-water-adding ports. After adding water, close the battery cover in time and screw it tightly to prevent the water from evaporating. Before adding water, first check whether the battery level is lower than the indicator line. Only when the liquid level is lower than the indicator line do you need to add water. Use distilled water or Deionized water to add water. Do not use tap water or other water containing impurities to avoid affecting the battery's working effect. When adding water, pour water slowly to avoid splashing on the battery casing or other components to avoid short circuit or other failures. Adding too much water would cause the battery to overflow, reduce performance, accumulate water in the box, and corrode. In serious cases, it might cause the battery to short-circuit. Therefore, it is necessary to add a small amount of water many times. It is strictly forbidden to add too much water to exceed the maximum liquid level.

The acid melting pool was a device used to deal with waste and pollution. Its working principle was to decompose organic matter and release chemicals by heating and melting acid. If the acid melting pool was used to clean up waste and pollution during the apocalypse, the acid released by the acid melting pool might have a serious impact on the surrounding environment. Acid can cause great harm to plants and animals and may even lead to their death. At the same time, the acid would cause serious pollution to the surrounding soil and water, causing the collapse of the ecosystem. Therefore, using an acid melting pool to deal with waste and pollution during the apocalypse could lead to serious consequences. The way the acid dissolving pool was used to deal with waste and contamination needed to be used carefully and the surrounding environmental conditions needed to be taken into account to ensure that the negative effects were minimized.
