WebTwo specific heats are defined for gases, constant volume (c v), and constant pressure (c p). According to the first law of thermodynamics, for a constant volume process with a monatomic ideal gas, the molar specific heat will be: C v = 3/2R = 12.5 J/mol K. because. U = 3/2nRT. It can be derived that the molar specific heat at constant pressure is: WebThe constant pressure specific heat, denoted as Cp, is the amount of heat required to raise the temperature of one unit of mass of a substance by one degree Celsius at constant pressure. For an ideal gas, the value of Cp depends …
