## Heat and Entropy

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### Heat and Entropy

Why would you need to use the heat equation before solving for entropy with a temperature change?

Since this equation for entropy change is in the form ∆S=nCln(T2/T1), you could use the "heat equation" q=nC∆T to solve for C if you know q, which you would then use for the entropy calculation.

### Re: Heat and Entropy

multiple steps allow you to figure out the values all components necessary to use the formula

### Re: Heat and Entropy

It is a multi-step process where first you use q=nCΔt and rearrange the equation to solve for the specific heat because the specific heat is needed to solve for ΔS=nCln(T2/T1).
