A diatomic ideal gas such as air, for which γ = 1.4, expands adiabatically to 40 times its original volume.
(a) By what factor does the temperature change?
(b) By what factor does the pressure change?
I'm not sure how to attempt/approach this one. If anyone has any suggestions, it would be greatly appreciated.
I tried using the equation T = T(not) - (mgh/R)*(gamma-1/gamma) but I didn't get anywhere, because I'm not sure where the expanding 40 times it's original volume comes in.
