The amount of heat absorbed when 1 kg of saturated liquid water boils at pressure P is Q1. The amount of heat released when 1 kg of saturated water vapour condenses at same pressure P is Q2, then
1
Q1 = Q2 for all values of P
2
Q1 > Q2 for all values of P
3
Q1 < Q2 for all values of P
4
Q1 > Q2 or Q1 < Q2 depends upon value of pressure P.
