Q: Argon gas is adiabatically compressed to half its volume. If P, V and T represent the pressure, volume and temperature of the gaseous system, respectively, at any stage, then the correct equation representing the process is

(a) TV2/5 = constant

(b) VP5/3 = constant

(c) TP-2/5 = constant

(d) PT2/5 = constant

Ans: (c)
For monoatomic gas γ=5/3
