如果我们测量热力学量会发现自由焓的变化,等于4千焦,正4千焦。,delta,H,is,4,kiloJoules,,plus,4,kiloJoules。,熵增dS是45焦耳每开尔文。
If we measure the thermodynamics, we discover that dH Delta S is 45 joules per Kelvin.
我们发现自由焓的变化,为负92千焦,negative,92,kiloJoules。,熵增dS是负198焦耳每开尔文。
Well, here we get, we find that delta H is dH Delta S is negative 198 joules per Kelvin.
我们得到了自由焓的变化,和和熵增dS的符号与大小,of,delta,H,and,delta,S,如果我们想要计算内能的变化,会发生同样的事情。
So clearly, we've got signs and magnitudes dH and if we wanted to put delta u there, similar things would happen.
