Formula and explanation
Formula: Q = Δ U + pΔ V Applicable conditions: Isobaric process of an ideal gas (constant pressure p ). Explanation: The heat added to the system ( Q ) is partly used to increase internal energy ( Δ U ) and partly used to do work on the surroundings ( pΔ V ). Here, Δ V is the change in volume.
