Specific Heat Capacity Measurement
It is constant characteristics of the substance and is independent of the amount of substance. It also depends on the temperature of the substance Its unit is J Kg -1 K -1 If the amount of substance is specified in terms of numbers of moles n instead of mass m then the heat capacity per mole of the substance is. It is constant characteristics of the substance and independent of the amount of substance It depends on the nature of the substance ,temperature and amount of heat supplied Its unit is J mol -1 K -1 In case of gases , when a gas is heated, ordinarily there is change in volume as well as pressure in addition to change in temperature For simplicity either volume or pressure can be kept constant. Our aim is to help students learn subjects like physics, maths and science for students in school , college and those preparing for competitive exams. All right reserved.

In thermodynamics , the specific heat capacity symbol c p of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. Informally, it is the amount of energy that must be added, in the form of heat , to one unit of mass of the substance in order to cause an increase of one unit in temperature. The specific heat capacity often varies with temperature, and is different for each state of matter. The specific heat of a substance, especially a gas, may be significantly higher when it is allowed to expand as it is heated specific heat at constant pressure than when is heated in a closed vessel that prevents expansion specific heat at constant volume. Specific heat relates to other intensive measures of heat capacity with other denominators.

Specific Heats at Low Temperatures pp Cite as. To some extent this is not surprising, because the limiting cases of solids and gases are sufficiently clear-cut and simple to allow schematic models to represent their behavior. In gases, the molecules are far apart and have no spatial correlation.
