1度电是输入功率为1kw的加热器或其他电器在1h内所消耗的电能。据科学测算，1度电可产生3614J（864千卡）的热量。那么1度电可加热多少水呢？水的比热CP为1，水的温差（即热水水温一进水水温）用凸T表示，热水器的热效率一般为80％，用问；表示。设被加热的水为GL，l度电产生的 1 kWh is the input power of 1kw heater or other electrical energy consumed within 1h. According to scientific calculations, 1 degree of electricity can generate 3614J (864 kcal) of heat. Then how much water can be heated by 1 degree electricity? The specific heat of water CP is 1, the water temperature difference (ie hot water temperature of a water temperature) with convex T said, the water heater thermal efficiency is generally 80%, with asked; said. Set the heated water to GL, l kWh
