Answer :
In a real isothermal expansion, the temperature of the surroundings must be equal to the temperature of the gas.
What is isothermal expansion?
Isothermal expansion is a condition in which gas expands from initial volume to final volume at a constant temperature.
- The change in temperature is zero.
- Isothermal processes take place in different kinds of systems from high structure machines to living cells.
- The enthalpy changes and internal energy depends on temperature.
- Carnot Engine can be an example of isothermal expansion.
