Question

In isothermal expansion of an ideal gas,does heat relased to sorroundings always??

Answer 1

Explanation:

Please mark it as brainlist....

This is a consequence of Joule's second law which states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. Thus, in an isothermal process the internal energy of an ideal gas is constant. ... For isothermal expansion, the energy supplied to the system does work on the surroundings
