Specific heat constant volume air

WebMay 22, 2024 · Two specific heats are defined for gases, one for constant volume (cv) and one for constant pressure (cp). According to the first law of thermodynamics, for constant volume process with a monatomic ideal gas the molar specific heat will be: Cv = 3/2R = 12.5 J/mol K because U = 3/2nRT
