Question

The heat absorbed or released during a process at constant pressure is called:
Options
A Internal energy change
B Enthalpy change
Correct Answer
C Work done
D Entropy change
Correct Answer

Option B is the correct answer.

Detailed Explanation

Enthalpy (H) is a thermodynamic function defined as H = U + PV. The change in enthalpy (ΔH) is equal to the heat transferred at constant pressure, provided only P-V work is done.

Hint

This is the defining relationship between heat at constant pressure and a state function.
