Work Done in Thermodynamics

Work Done in Thermodynamics

Work is energy transfer due to volume change of a system.

### Formula

$$W=P\Delta V$$

### For Variable Pressure

$$W=\int PdV$$

### Terminologies

- W → Work done.

- P → Pressure.

- ΔV → Change in volume.

### SI Unit

$$Joule(J)$$

### Conditions / Special Cases

Expansion:

$$W>0$$

Compression:

$$W<0$$

### Usage

- Used in thermodynamic processes.
