初中物理第二册第16页有一个证明“温度越高，分子无规则运动越激烈”的实验：把分别盛有冷水和热水的两个玻璃杯放在桌上，小心地在每杯中滴入两滴墨水，不搅动杯中的水，观察两杯水中墨水的扩散过程，看热墨水和冷墨水哪个扩散得快‘当在热水杯和冷水杯中各滴入一滴墨水后， In the second volume of the junior high school physics book, there is an experiment that proves that “the higher the temperature is, the more intense the random movement of the molecules”: put two glasses of cold and hot water on the table, carefully in each cup. Instill two drops of ink, without stirring the water in the cup, observe the diffusion process of the ink in the two cups of water, see which of the hot ink and the cold ink spreads quickly. When a drop of ink is dropped into the hot and cold cups,
