The heat absorbed by a system at constant pressure is equal to $\Delta$E + P$\Delta$V.

Question

Quizplus · Accepted Answer

This is the statement of the first law of thermodynamics for a system at constant pressure. The heat absorbed (Q) is equal to the change in internal energy (ΔU) plus the work done (PΔV) on the surroundings. The formula given in the question is just a different way of writing this equation, where F1F1F1S1 represents the final state of the system and F1F1F1S0 represents the initial state.
