To find the relationship between enthalpy (ΔH) and internal energy change (ΔU), we can follow these steps: ### Step 1: Understand the definitions Enthalpy (H) is a thermodynamic quantity that represents the total heat content of a system. It is defined as: \[ H = U + PV \] where: - \( H \) is the enthalpy, - \( U \) is the internal energy, ...
