Water Vapor - Specific Heat vs. Temperature

Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree. This tool provides isobaric specific heat (Cp) values for water vapor (H2O) at temperatures ranging from 175 K to 6000 K, useful for calculating mass and volume flow of heated or cooled systems with high accuracy.
