A gas absorbs 100 J of heat and has 30 J of work done on it. What is ΔU? In the AP convention, what is the sign of W when a gas expands? What does the area under a curve on a PV diagram represent? For an ideal gas in an isothermal process, which statement is true? In an adiabatic compression, the temperature of an ideal gas What is the net change in internal energy of a gas over a complete cycle? An engine absorbs 400 J and rejects 300 J. What is its efficiency? Which temperatures belong in the Carnot efficiency formula? What does a clockwise loop on a PV diagram mean? Heat Q flows into a reservoir at temperature T. What is its entropy change? First law of thermodynamics — ΔU = Q + W (W is work on the gas) Work at constant pressure — W = −pΔV Meaning of area under a PV curve — Magnitude of the work Internal energy of a monatomic ideal gas — U = (3/2)nRT Isothermal ideal gas: ΔU equals what? — Zero, so Q = −W Adiabatic process: Q equals what? — Zero, so ΔU = W Engine efficiency — e = W_net/Q_H = 1 − Q_C/Q_H Carnot efficiency — e_max = 1 − T_C/T_H (kelvin) Entropy change for heat Q at T — ΔS = Q/T Second law in one line — Total entropy never decreases Keep going with Lina
