Question

Is it true that it takes more energy to vaporize 1 kg of saturated liquid water at 100 C than it would at 120 C?​

Answer 1

Answer:

There is no change in temperature until the phase transition is complete, at which point the temperature changes. Latent heat is measured in joules per kilogram of body weight. The process of vaporizing water requires much more energy; it would need 2256 kJ to convert 1 kilogram of liquid water at the standard boiling point (100oC at atmospheric pressure) to steam (water vapor).
