One is that he observed when people were machining cannon barrels, a lot of heat was generated, and there was a lot of work done.
第一种说法说焦耳发现,制作加农炮筒时,会产生大量的热,同时这中间有大量的做功。
It'll be hotter. How much hotter? Well, that depends on how much heat was produced.
它会更热一些,更热多少?,这取决于产生了多少热量。
And so maybe the work generated the heat.
因此或许功产生了热。
So in principle, if I measure how much hotter, I can determine how much heat was produced, and from that, I should be able H to calculate delta H at T1.
所以原则上,如果我测量,变热了多少,我就能确定,有多少热被产生,从中我就可以计算T1下的Δ
