What is q equal to in the second law of thermodynamics?
As in how would it be presented in a problem and in what units?

The second law of thermodynamics states that delta S=q/T=nRln(V2/V1). So q=nRTln(V2/V1) if you multiply both sides by temperature. I believe the unit for q is Joules.

Wouldn't you have to divide rather than multiply both sides by T?

T can be completely canceled out. Think of it as the -q=w. Because the function for work involves the multiplication of T but deltaS is q/T, the q is simply taken out and the negative sign is omitted.

I believe its divide;.

Thanks Ben that helps!!!
