Text Solution

AI Generated Solution

To determine the conditions under which ΔH (change in enthalpy) becomes equal to ΔU (change in internal energy), we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Relationship Between ΔH and ΔU**: The relationship between enthalpy (H) and internal energy (U) is given by the equation: \[ H = U + PV ...
