Change in S with changes in P, V, and T

[Justin Lau 1D]

What specific heat capacity is to be used for an ideal gas when there are changes in P, V, and T as pressure and volume are both not constant? Is it even possible for all three to be changed together?

[Jingyi Li 2C]

It is not possible for all three to change simultaneously. When T changes, you use the formula with the heat capacity. The problem would tell you if the reaction is under constant P or V, then you would know which heat capacity to use.

I'm in agreement with the statement above - we're probably not going to be asked for all three to change because that would be impossible to calculate with what we know about heat capacities for ideal gases.

You wont be asked a problem with all three of those being unknown because its not possible to calculate one without the other 2
