For 10 points, the Carnot cycle pairs two isothermal processes with what type of process that has no heat transfer?
One technique named for this adjective was first performed using gadolinium phosphomolybdate tridecahydrate by William Giauque ("jee-OAK"). In that process named for this adjective, a paramagnetic salt in equilibrium with a liquid helium bath is first magnetized, then the helium is removed and the temperature drops to values as low as 1 millikelvin due to this type of (*) "demagnetization." A steeply-sloped hyperbola on a PV diagram represents this type of process, for which the product of pressure times volume raised to the power of the heat capacity ratio is constant. A process that is reversible and has this property is isentropic. For 10 points, the Carnot cycle pairs two isothermal processes with what type of process that has no heat transfer?
