What energy will be released during the condensation of water vapor with a mass of 5 kg

What energy will be released during the condensation of water vapor with a mass of 5 kg, having a temperature of 100 degrees, into water at the same temperature?

The amount of heat energy released during condensation of water vapor is calculated by the formula:

Q = L * m, where L is the specific heat of vaporization of water (L = 2.3 * 10 ^ 6 J / kg), m is the initial mass of water vapor (m = 5 kg).

Let’s calculate the released amount of heat energy:

Q = L * m = 2.3 * 10 ^ 6 * 5 = 11.5 * 10 ^ 6 J = 11.5 MJ.

Answer: When condensing 5 kg of water vapor, 11.5 MJ of thermal energy will be released.
