[abstracted6]

Homework Statement

Show that in a reversible adiabatic process, for 1 mole of ideal gas

P₁V₁^γ=P₂V₂^γ

Where,

γ=C_P/C_V

Homework Equations

Listed above.

The Attempt at a Solution

Frankly, I don't really understand what I'm being asked to do.

It simply meant to ask that PV^γ is constant for a reversible adiabatic process. Actually, the question is asking to prove that the adiabatic processes follows this trend, just like PV=constant for isothermal processes.

Try the question. A good one indeed.
