univerkov | October 5, 2021 | education

Problem data: m (initial mass of water vapor) = 2.5 kg.

Reference values: L (specific heat of condensation of water vapor) = 23 * 10 ^ 5 J / kg.

The amount of heat that will be released during the condensation of 2.5 kg of water vapor is calculated by the formula: Q = L * m.

Let’s make the calculation: Q = 23 * 10 ^ 5 * 2.5 = 57.5 * 10 ^ 5 J (5.75 MJ).

Answer: When condensation of water vapor with a mass of 2.5 kg, 5.75 MJ of heat is released.
