melting ice cubes冰块融化是冰从固态变为液态的物理变化过程,其本质是温度升高导致分子动能增加。该现象受环境温度、压力及接触介质影响,具有科学教育价值和实际应用意义。下文将从物质相变原理、加速融化方法、实验教学应用三方面展开分析。 一、物质相变的微观机制 冰块融化属于相变中的固...
The ice cube in the metal pot was the first to melt. It happened very quickly. The other ice cubes took much longer to melt. Our next ice cube to barely begin to melt was on the thin glass cutting board. The other ice cubes were still frozen. This is what the ice cube in the me...
