Specific heat capacity

[fani98]

can anybody tell me how the specific heat capacity varies with pressure and temperature for superheated vapors
thanks

all i know as specific heat capacity is = Q / M (theta), there is an inverse effect on theta (temperature) and specific heat capacity, as temp increases SHC decreases!

The specific heat capacity of a substance is the amount of energy required to raise the temperature of one gram of that substance by one degree Celsius. This value can vary with changes in pressure and temperature, particularly for superheated vapors.

As pressure increases, the specific heat capacity of a superheated vapor typically decreases. This is because higher pressure results in a denser vapor, which has less space for the molecules to move and vibrate, leading to a decrease in heat capacity.

On the other hand, as temperature increases, the specific heat capacity of a superheated vapor generally increases. This is because at higher temperatures, the molecules have more energy and are able to move and vibrate more, requiring more energy to increase their temperature.

It is important to note that the specific heat capacity of a substance is not a constant value and can vary based on a variety of factors, including pressure and temperature. Therefore, it is important to consider these variables when studying the properties of superheated vapors.
