Two cylindric A and B of equal capacity are connected to each other via a stopcock . A contains a gas STP. , B is completely
evacuated, the entire system is thermally insulat ed .. The stopcock is suddenly op ened ans
What is the final pressure of he gas in A and B
what is the change in internal energy of the gas
what is the change in temperature of the gas
Pls give the reason also

Solution

(a) The gas would rush from A to B. The change in pressure or volume will take place under adiabatic conditions. The final pressure in the two cylinders would be 0.5 atm.
(b) The change in internal energy of the gas will be zero.
(C)The change in temperature will be zero.

Two cylinders A and B of equal capacity are connected to each other via a stopcock. A contains a 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?

(d) Do the intermediate states of the system (before settling to the final equilibrium state) lie on its P-V-T surface?
