Specific Heat (Cp) Measurements
Specific heat capacity or specific heat under constant pressure (Cp) is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius. Specific heat is an important value that can be used to determine the amount of heat or energy transferred between a system and its surroundings. The specific heat of a substance is an intensive property of that substance, meaning it does not depend on the size or volume of that substance. If mass and specific heat of a substance are known, then the change in the substance’s temperature (ΔT) will reflect the amount of heat (q) absorbed or released in a particular process following the relationship: q = (mass of the substance)(Cp)(ΔT).
