💡 Solution & Explanation

The enthalpy of an ideal gas depends only on its temperature ($H = U + PV = U(T) + nRT$), making it a function of temperature alone. Therefore, at constant temperature, $\Delta H = 0$. Statement I is correct, but Statement II is incorrect because enthalpy does not depend on pressure for an ideal gas.
