We're not going to have the constant pressure heat capacity, we're going to have the constant volume heat capacity, right.

这里出现的,不是等压热容,而是等体热容。

And our heat of reaction or enthalpy of reaction is defined as the enthalpy at constant pressure.

我们的反应热，或反映,的焓被定义为恒压，等温。

So the expansion against lower pressure draws less heat from the hot reservoir right.

所以压强较低时的膨胀,从高温热源吸收的热量更少。

Here we have a fixed volume, and we have a little candle, and we're adding heat, and when we add heat, the pressure does what?

这里我们有一个容器，一个蜡烛，然后我们加热，这时压强会怎么变化？

Cp And delta T is given by the heat, which has to do with how much of the candle burnt, divided by the constant pressure heat capacity.

T等于热量q除以恒定的等压热容，其中热量与，蜡烛燃烧的多少相关。

Over here, we have dq=Cp dT, the heat, the proportionality between heat - and temperature rise is given by this, the constant pressure heat capacity.

这里我有dq=CpdT，这是热量，这是联系热量,和温度变化的系数，恒压热容。
