What is the specific heat of a gas in an isentropic process pv^n = constant?
Answers
Explanation:
How much does a given amount of heat transfer change the temperature of a substance? It depends on the substance. In general
$\displaystyle Q = C\Delta T,$ (2..4)
where $ C$ is a constant that depends on the substance. We can determine the constant for any substance if we know how much heat is transferred. Since heat is path dependent, however, we must specify the process, i.e., the path, to find $ C$ .
Two useful processes are constant pressure and constant volume, so we will consider these each in turn. We will call the specific heat at constant pressure $ C_p$ , and that at constant volume $ C_v$ , or $ c_p$ and $ c_v$ per unit mass.
The Specific Heat at Constant Volume
Remember that if we specify any two properties of the system, then the state of the system is fully specified
