1.雪櫃的power 指每second 供電入去定係佢每second take way heat?
2.放一支thermometer 入雪櫃, 過左一陣, 用temperature drop 多幾度, 計refrigerator ge power rate. 點解話計到既value 係大過實際refrigerator 既power rate? 同heat loss 有關係?

✔ 最佳答案
1. The power of a refrigerator usually refers to the power consumed by it.2. I don't know how you would measure the power of the refrigerator just from the drop in temperature of the thermometer. The thermometer only measured the temperature inside the refrigerator. The rate of fall in temperature as recorded by the thermometer would be very much dependent on the sensitivity of the termometer itself.
