[題目] A cube of water 10cm on a side is placed in a microwave beam having E0=10kV/m . The microwaves illuminate one face of the cube, and the water absorbs 82% of the incident energy. How long will it take to raise the water temperature by 42度C? Assume that the water has no heat loss during this time. [瓶頸] (寫寫自己的想法，方便大家為你解答) 這是我這一次masteringphysics的作業題目，答案是160，我看到熱我就用 H=ms(deltaT)來代，但我不知道產生的熱要怎麼表示。 希望高手教我解法，感謝。 --
