WebThe latent heat of vaporization of water is 22.5 × 10 5 joules per kilogram (or 22.5 × 10 5 j/kg). Hence it means that 22.5 × 10 5 J of heat is required to change 1 Kg of water (at its boiling point, 100°C) into steam at the same temperature of 100°C. What is the vaporization point of water? WebAug 8, 2024 · When 1 mol of water at 100 o C and 1 atm pressure is converted to 1 mol of water vapor at 100 o C, 40.7 kJ of heat is absorbed from the surroundings. When …
