HW 9.13
When calculating the entropy change due to the change in temperature, where does the the equation delta S = n R ln (t2/t1) come from in the solutions manual? Shouldn't the equation be delta S = n C ln(t2/t1)? And how are we supposed to assume that there are 1.00 moles of N2 gas without the problem explicitly stating it?

Re: HW 9.13
Since this question asks you to assume that the N2 exhibits ideal gas behavior, the variation of the entropy equation
S= nRln(T2/T1). Additionally, since the question mentions that the gas is ideal and no number of moles is otherwise specified, the number of moles in the container is implied to be 1 mole. For more information on this, refer to pg. 323.

Re: HW 9.13
I thought that the equation using R was only for volume or pressure (ΔS = nR ln(V2/V1)). Is it the same for temperature too? Where did that equation come from?
