A monatomic ideal gas, initially at temperature T1, is enclosed in a cylinder fitted with a frictionless piston. The gas is allowed to expand adiabatically to a temperature T2 by releasing the piston suddenly. If L1 and L2 are the length of the gas column before and after expansion respectively, then is given by
detailed solution
Correct option is D
Here TVγ−1= constant As γ=5/3,hence TV2/3= constant Now, T1L12/3=T2L22/3 (∵V∝L)or T1T2=L2L12/3Talk to our academic expert!
