Figure \(\PageIndex{3}\): An isothermal … WebThe work done by the gas is P2Ax2 = P2V2. Therefore the net external work done on the gas is P1V1 − P2V2 .) If no heat is supplied to or lost from the system, the increase in internal energy of this gas is just equal to this work done on it: U 2 − U 1 = P 1 V 1 − P 2 V 2, or (10.3.1) U 1 + P 1 V 1 = U 2 + P 2 V 2.

WebWhen the membrane is punctured, gas rushes into the empty side of the container, thereby expanding freely. Because the gas expands “against a vacuum” (p = 0) ( p = 0), it does no work, and because the vessel is thermally insulated, the expansion is adiabatic.
