An insulated container of gas has two chambers separated by an insulating partition. One of the chambers has volume and contains ideal gas at pressure and temperature . The other chamber has volume and contains ideal gas at pressure and temperature . If the partition is removed without doing any work on the gas, the final equilibrium temperature of the gas in the container will be
detailed solution
Correct option is A
As no work is done and system is thermally insulated from surrounding it means sum of internal energy of gas in two partitions is constant , i.e. U=U1+U2 Assuming both gases have same dof, then U=f(n1+n2)RT2And U1=fn1RT12,U2=fn2RT22Solving we get T=P1V1+P2V2T1T2P1V1T2+P2V2T1Talk to our academic expert!
