Question

Quizplus · Accepted Answer

The specific heat at constant pressure (Cp) can be calculated using the relation Cp = Cv + R/M, where Cv is the specific heat at constant volume, R is the gas constant, and M is the molar mass. Substituting the given values, Cp = 2.5 kJ/kg.K + (8.31 J/mol.K / 18 g/mol) = 2.5 kJ/kg.K + 0.4617 kJ/kg.K = 2.9617 kJ/kg.K, which is approximately 2.96 kJ/kg.K.
