我放学回来时,买完我爱吃的烤卤鸭后,在电瓶车上,我发现装卤鸭的袋子鼓起来了。
When I came back from school, after buying my favorite roast duck, in the battery car, I found the bag filled with marinated duck bulging.
我把这件事告诉了妈妈,妈妈说,她可从来没注意过这种现象,这件事真是奇怪透了!但是,我却知道其中的原理,因为煮熟的热食物将塑料袋子内的空气膨胀起来的,是热胀冷缩的原理在作怪!
I told my mother about it. She said that she had never paid attention to this phenomenon. It was so strange! However, I know the principle, because cooked hot food will expand the air in the plastic bag, which is the principle of heat expansion and cold contraction!
你若不相信的话,不妨来做个试验:把一个瓶子里灌满冷水,在把它放在火上烧,水烧开后,再不马上拿出来的话,瓶子就要爆炸了,现在你懂了吗?
If you don't believe it, you can do an experiment: fill a bottle with cold water, put it on the fire and burn it. If the water is boiled and doesn't come out immediately, the bottle will explode. Do you understand now?
