(1 ) A 20kg sample of pure water at 40℃ is mixed with 20kg sample of pure water at 32℃,Using the average temperature of each sample,deternime the approximate net change in entropy of the total quantity of water.The apecific heat of pure water is 4186J/kg.K
（2）A nuclear power plant operates at 75 percent of its maximum theoretical efficency between temperatures of 660℃ and 360℃.If the plant produces electric energy at the rate of 1.1 GW,how much exhaust heat is discharged per hour?

去看看你的英语老师吧,他(她)也许可以帮到你,如果不能的话,也许可以给你准确的翻译出来,再做物理就简单多了.
再问：那麻烦你翻译一下吧，谢谢~~
再答：我是用金山词霸翻译的,可能不太正确哦!有些专用名词根本不是那么回事儿.(是否正确我觉得你应该找个专业人事看一下) （1）一个连续抽样的纯净水在40℃混合样本的纯净水在32℃，使用的平均温度的每个样品，观察近似12130熵的总水量。这比热的纯净水4186j钾/公斤。（2）一个核电站运行在百分之75的最大理论效率之间的温度为660℃和360℃。如果该厂生产的电能的速度在1.1千瓦，多少余热排出每小时吗？
