A sample of one.00 mol perfect gas molecules with $C_{p,\mathrm m} = 7R/2$ is put through the post-obit cycle: (a) constant-volume heating to twice its initial volume, ...

(Problem 2.five, Atkins Physical Chemistry 8th ed.)

The problem says that in a constant volume process the final volume is twice the initial volume.

Is this fifty-fifty possible? How can volume get twice if information technology was constant all the time, information technology wouldn't have exploded to twice its size suddenly later the process concluded right?

  • $\begingroup$ The question is apparently wrong. What'due south your source? $\endgroup$

  • $\begingroup$ @ToddMinehardt Physical Chemistry by Peter Atkins 8th ed. I took it from my school library. $\endgroup$

  • $\begingroup$ @ToddMinehardt the 8th ed of Atkins indeed has this weird question: i.stack.imgur.com/enri8.png. The question has been removed in the 10th ed. It is very plain wrong, I doubtable it was meant to be constant pressure level. $\endgroup$

  • $\begingroup$ Next fourth dimension, please include the source with it, and quote information technology verbatim. That allows people to better guess what'south going on. $\endgroup$

  • $\begingroup$ @orthocresol Yeah I do and then next time I ask a question. $\endgroup$
