What is enthalpy and how does it change during heat transfer at constant pressure?
gpt
Enthalpy is the transfer of energy; it increases when heat is absorbed by a system at constant pressure and decreases when heat is released by a system at constant pressure.
Explanation: Enthalpy is a thermodynamic property that represents the energy transferred due to heat at constant pressure, and its change indicates the energy flow into or out of a system.
