One mole of an ideal gas at 300 K is expanded isothermally from an initial volume of 1 L to 10 L. Th — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

For an ideal gas, internal energy is a function of temperature only. Since the process is isothermal ($\Delta T = 0$), the change in internal energy ($\Delta U$) must be exactly zero.
