Entropy Change at Constant Pressure

Entropy Change at Constant Pressure

### Formula:

$$\Delta S=nC_p\ln\frac{T_2}{T_1}$$

### Terminologies:

- ΔS → Entropy change.

- n → Number of moles.

- C_p → Heat capacity at constant pressure.

- T₁, T₂ → Initial and final temperatures.

### Usage:

- Used when pressure remains constant.
