Define an isothermal process and state two essential conditions for such a process to take place.

Text Solution

Verified by Experts

The correct Answer is:
Isothermal process: An isothermal process is one, in which the pressure and volume of the system change but temperature remains constant. Conditions: For an isothermal process to take place
(i) the cylinder should have conducting walls and
(ii) the gas should be compessed or allowed to expand very slowly.
