Question 8.31a on homework

Postby Alyssa Parry Disc 1H » Thu Jan 11, 2018 7:29 pm

In the answer for 8.31a, what is the significance of Cp,m=5/2R. Is that supposed to be the molar heat capacity? If so, how would we calculate that using that formula?

It is the heat capacity of monatomic ideal gases at constant pressure. Constants are found on page 281. I believe you calculate heat with q=(mol of substance)(heat capacity=5/2R)(temp change). :)
