Physics · Thermodynamics
A monoatomic ideal gas initially at temperature T1 is enclosed in a cylinder fitted with a massless, frictionless piston. By releasing the piston suddenly, the gas is allowed to expand adiabatically to a temperature T2. If L1 and L2 are the lengths of the gas columns before and after expansion respectively, then the ratio T2T1 is equal to:
