Entropy Change for Ideal Gas

Entropy Change for Ideal Gas

### Formula:

$$\Delta S=nC_v\ln\frac{T_2}{T_1}+nR\ln\frac{V_2}{V_1}$$

### Terminologies:

- ΔS → Entropy change.

- n → Number of moles.

- C_v → Heat capacity at constant volume.

- T₁, T₂ → Initial and final temperatures.

- V₁, V₂ → Initial and final volumes.

- R → Gas constant.

### Usage:

- Used to calculate entropy change of ideal gases.
