同学们在学匀浮力有关知识后,经常会遇到一系列似曾相识的应用问题,例如出现类似水中各种情况冰熔化后水面高度怎么变的问题,对于这类问题,大家都感觉到比较困惑。实际上,这类似问题的解决必须在思路上进行突破。现将其解题思路总结为:先比较冰熔化前后浮力变化,根据阿基米德定律 After learning about buoyancy, the students often encounter a series of familiar problems. For example, the problem of how the height of the water surface changes after ice melts in various conditions in the water. Everyone feels confused about this type of problem. In fact, the solution to this similar problem must be a breakthrough in thinking. The problem-solving train of thought is summarized as follows: first compare the buoyancy changes before and after ice melting, according to Archimedes’ law
