Condensation is a process for which O AG is negative at high temperature but positive at low temperature. O AH, AS, and AG are positive at all temperatures. AG is positive when condensation occurs spontaneously. O AH and AS are positive at all temperatures. O AH and AS are negative at all temperatures.
