Ideal Gas Heat Capacity at Constant Pressure - Metric Units

Ideal Gas Heat Capacity at Constant Pressure - Metric Units These tables are for the Heat Capacity of isobaric (constant pressure) ideal gasses at different tempeartures. Isobaric means that the pressure is held constant as the temperature increases. This is designated as C_p in most equations in heat transfer. Units: kJ/(kg K)
