Physical chemistry book gives an example of a closed system of gas being heated, but then expanding a piston outward in a cylinder, performing work on the surroundings. It uses this as an example of an isothermal expansion (stating that isothermal means temp of gas is same initial and final). My understanding: But if PV=nRT, and n is UNchanged, then an increase in V (from heating) must be accompanied by an increase in T!!!
