Q 1929701611.     Two cylinders A and B of equal capacity are
connected to each other via stopcock. A
contains gas at standard temperature and
pressure, B is completely evacuated. The
entire system is thermally insulated. The
stopcock is suddenly opened. Answer the
following:
(a) What is the final pressure of the gas in
A and B?
(b) What is the change in internal energy of
the gas?
(c) What is the change in the temperature of
the gas?
(d) Do the intermediate states of the system
(before settling to the final equilibrium
state) lie on its P-V-T surface?
