How much heat will be released during the condensation of 2 kg water vapor taken at a temperature of 100 C.

The amount of heat is calculated by the formula Q = Lm, m is the body weight in kg, L is the specific heat of condensation (and vaporization). L is a tabular constant, for water L = 2.3 * 1,000,000 (or 10 to the power of 6) Joule / kg. Q = 2.3 * 1,000,000 J / kg * 2 kg = 4,600,000 Joules, can be converted to Megajoule. 1 MJ = 1,000,000 J 4,600,000 = 4.6 MJ
Answer: 4.6 MJ of energy will be released (or 4.6 * 10 to the 6th power of J)
