Air (γ = 1.4) is pumped at 2 atm pressure in a motor tyre at 20°C. If the tyre suddenly bursts, what would be the temperature of the air coming out of the tyre. Neglect any mixing with the atmospheric air.

Given γ = 1.4,


Initial pressure, P1=2 atm


Final pressure, P2=1 atm


Initial Temperature, T1=20°C=293 K


Here bursting of tire is an adiabatic process,
