Question

Derive the relationship between enthalpy and internal energy at constant temperature and pressure

Answer 1

Explanation:

Enthalpy is also known by the term `heat content'. Considering ∆U = q -w or q - P∆V (assuming P- V work), ∆U + P∆V becomes equal to 'qp'. ... Heat effects measured at constant pressure indicate changes in enthalpy of a system and not in changes of internal energy of the system
