n=0,pv^0=constant.i .e.,isobaric process (p=const).
n=1,pv=const.i.e., Isothermal process (temperature= const).
n=gama,pv^gama=const.i.e., Isentropic process.
n=infinity,pv^infinity=consnt.i.e.,v= const i.e, isochoric process (v= const).
n=1,pv=const.i.e., Isothermal process (temperature= const).
n=gama,pv^gama=const.i.e., Isentropic process.
n=infinity,pv^infinity=consnt.i.e.,v= const i.e, isochoric process (v= const).

There are three basic processes:
1. pv^n = c is polytropic process.
2. pv^gamma=c is an adiabatic process.
3. pv=c is isothermal process.
1. pv^n = c is polytropic process.
2. pv^gamma=c is an adiabatic process.
3. pv=c is isothermal process.

n=0 Isobaric.
n=1. Isothermal.
n>1. Polytropic.
n=gamm. Adiabatic.
n=infitniy Constant volume.
n=1. Isothermal.
n>1. Polytropic.
n=gamm. Adiabatic.
n=infitniy Constant volume.

We know anything raise to 0 is 1 so v=1 and p*1=c i.e. p=c therefore constant pressure process.

If anything to the power zero is value zero V power 0 is zero so P is equal to c (constant).

Its wrong, this is according to thermodynamics second law and einstein 2nd law.

p*1=c that is p=c hence the process is at constant pressure process.

IT' S WRONG ("PV = MRT = C"{MEANS (CONSTANT TEMPERATURE PROCESS)).

When n=0, the equation may write as p=c.
So pressure is constant.
So pressure is constant.

If n=0 then p=C hence we can say that pressure constant process.
