论文部分内容阅读
●bowl(碗) ●boiling water (开水)●wooden spoon(木勺子)
●metal spoon (金属勺子) ●plastic spoon (塑料勺子)●dried peas (干豆子)
●butter (黄油,或者用凝结起来的猪油也可以噢)
Look, the butter on the metal spoon melts first. Wood and plastic are poor heat conductors, so it takes longer for the butter to melt on them.
瞧,金属勺子上的黄油首先融化。木头和塑料是不太好的热导体,所以它们需要更长的时间,才能让黄油融化。
