The heat burns off a small amount of heart muscle.

Now, the coefficient that relates the amount of heat in to the temperature change is obviously going to be different for these two cases.

在这两个例子中,很显然联系热量和温度变化的系数,是不一样的。

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。

So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.

重要的信息，如果我们看看,这些不同种类的光，微波,如果被分子吸收，它的频率和能量可以,使分子转动,这当然的，会产生热量,这就是你们微波炉的工作原理。

Heat capacity relates the amount of heat that you add to the system to the change in temperature, and this is the relationship.

热容联系起给系统提供的,热量和温度的变化，关系式是这样的：

OK, so that means heat is being imparted to the system, right, from the surroundings in a manner that compensates exactly the amount of work done.

好，这表示系统,从外界吸热,吸收的热量与系统,对外做功的值相等。

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。
