| 1) | In this, temperature remains constant | 1) | In this, no heat is added or removed |
| 2) | It occurs slowly | 2) | It occurs suddenly. |
| 3) | Here, system is thermally conducting to surroundings | 3) | Here, system is thermally insulated from surroundings. |
| 4) | State equation :→ PV = constant | 4) | State equation : → PVY = constant. |

Process in which temperature remains constant throughout the process is called isothermal process. When such a process occurs, heat can flow from the system to the surrounding and vice versa in order to keep the temperature constant. In an isothermal process, dT= 0.
When a process is carried out in such a way that no heat can flow from the system to the surroundings or vice versa i.e., system is completely insulated from the surroundings. In such a system, temperature of the system always changes. For an adiabatic process dQ = 0
