# Constant term in the adiabatic equation

by mechgen
 P: 3 Hi there! I am working on a project that requires some idea of adiabatic processes. I know the basics of the said topic and I'm currently stuck with the reversible adiabatic equation PV^(gamma)=constant.. and want to know what is the constant term i.e. on what parameters it depends and what is its mathematical equation? Kindly help me if you can...
 P: 925 It is a constant,right.Then why should it depend on anything.
 PF Patron Thanks P: 2,989 $$PV^{\gamma}=P_1V_1^{\gamma}$$ where P1 and V1 are the initial pressure and volume.

## Constant term in the adiabatic equation

 It is a constant,right.Then why should it depend on anything.
well as far as I know...a constant term doesn't mean that it doesn't depend on any other parameter. Take the ebullioscopic constant for instance..that depends on certain values of specific heat and and the temperature etc... I hope you get my point!
 P: 925 well,for adiabatic process it means that if system is going under adiabatic change then that Pv^gamma would not change.
