During a small change in the temperature of a substance, Cv is the amount of heat energy absorbed/released per unit mass of a substance where volume does not change. WebYes, if you were dealing with an ideal gas the ideal gas law would still apply which could be used to calculate (in addition to number of moles) temperature, pressure, and volume of the gas. Since the ideal gas law is: PV = nRT, it has four variables (P, V, n, and T), we would need to know three of the four to calculate the fourth variable.

In thermodynamics, the specific heat capacity (symbol c) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg ⋅K .
