火柴是我们日常生活中的常见用品,将火柴用来做物理实验,可以收到很好的效果。1.摩擦生热:火柴盒两侧的火药皮中含有红磷,当火柴头与火柴盒药皮摩擦时,就会摩擦生热,从而使火柴头触及的部位温度升高,引起红磷着火,此实验简单易操作,且实验效果明显。 Matches are a common item in our daily lives. Using matches for physical experiments can produce very good results. 1. Friction and heat generation: Red phosphorus is contained in the skin of gunpowder on both sides of the match box. When the head of the match is rubbed with the skin of the match box, it will generate friction heat, which will increase the temperature of the parts touched by the match head and cause red phosphorus to ignite. This experiment is simple and easy to operate, and the experimental results are obvious.
