A car tyre is slowly pumped up to a pressure of 2 atm in an environment at 15 C. When the tyre bursts, the pressure of the gas pumped in to the tyre is equal to 1 atm. It is assumed that the volume of the gas remains the same momentarily. In an adiabatic process there is no exchange of heat to the environment.
Use the ideal gas law: PV = n*R*T
Initially 2*V = n*R*15 ...(1)
After the explosion, 1*V = n*R*T' ...(2)
=> 1/2 = T'/15
=> T' = 7.5
The required temperature of the gas is 7.5 C
