One molarA sample of a ideal1.00 mol perfect gas molecules with $C_{p,\mathrm m} = 7R/2$ is put through the following question cycle: (a) - constant volume heating to twice its original volume (b)constant-volume heating to twice its initial volume, ...
(Problem 2.5, Atkins Physical Chemistry 8th ed.)
The problem says that in a constant volume process the final volume is twice the initial volume.
Is this even possible ? How can volume become twice if it was constant all the time, it wouldn't have exploded to twice its size suddenly after the process ended right ?
Though this thread contains a "homework" question I don't think I need to provide my effort as I am giving an example of a question to ask something else. I think this is equivalent to citing a source and asking some question about it.
