One mole of an ideal gas expands isothermally and reversibly at 0°C. The pressure on 1 mol of an ideal monatomic gas changes from 100.0 atm to 1.00 atm.Calculate ΔE.

Question

Quizplus · Accepted Answer

For an ideal gas undergoing an isothermal process, the change in internal energy (ΔE) is zero because internal energy is a function of temperature, and the temperature remains constant in an isothermal process. Since the temperature does not change, there is no change in the kinetic energy of the gas molecules, and thus no change in internal energy. None of the provided options match this explanation.
