A thermodynamic process is a change in the state of a system characterized by its thermodynamic variables (e.g., pressure, volume, temperature). It describes how a system transitions from one equilibrium state to another.
Two Types:
1. **Isothermal Process:** Temperature remains constant (\( \Delta T = 0 \)).
2. **Adiabatic Process:** No heat is exchanged with the surroundings (\( Q = 0 \)).
Answer: A thermodynamic process is a change in a system’s state. Types: isothermal, adiabatic.
