thanks,waiting online.
我在新加坡上学,这部分是出在latent heat of fusion,

因为水蒸发是吸热的,而温度升高加剧了水蒸发的速度,因此带走了大量的热,所以水变热后,温度上升的慢.
这才是问题的关键所在啊.

楼上回答正解
话说为什么要用英文提问呢- -?

楼上的 人家是不知道英文的意思 怎么中文提问啊

温差越大,热传递越快,火与温差变小,温差变小,水与空气温差变大,再加上水温升高,接近沸点,水蒸发加快,因此要吸收大量的热使之气化,所以,烧水时,水温上升越来越慢。

实际上,它是由英文设置,其能是“让trasons为什么温度升高得慢些水变得更热”,
感谢,在线等待。

散热率随温差的增加而增加,但供热率不变。
