As the lubricating oil passes over a hot engine part, it removes a certain amount of heat.
当机油经过发动机的热的部件时,它将带走一定量的热量。
So we don't really need to put in a certain amount of heat and change the temperature of the products and the calorimeter and so on.
所以我们实际上并不需要输入,一定的热量,改变生成物,和量热计的温度之类。
Even if you heat your house with electricity, the generation of the electrical power may also have emitted a certain amount of CO2.
就算你家的房子是用电采暖,电能产生的过程也是释放二氧化碳的。
So we don't really need to put in a certain amount of heat and change the temperature of the products and the calorimeter and so on.
所以我们实际上并不需要输入,一定的热量,改变生成物,和量热计的温度之类。
It's just how much heat is involved when we change the temperature. Now, the products have some heat capacity associated with them right, it takes a certain amount of heat if we make their temperature change, to either put it in or take it away, depending on which direction the temperature is changing.
问题就是当我们改变温度时,有多少热量发生了转移,生成物具有一定的热容,如果我们改变,它们的温度,就要输入或,提取一定的热量,这取决于温度改变的方向。
