An insulated container is divided into two equal portions. One portion contains as ideal gas at pressure `P` and tenperature `T`. The othe portion is a perfect vaccume. If a hole is opened between the two portions, claculate
a. the change in internal energy.
b. the change in temperature.

An insulated container is divided into two equal portions.One portion contains an ideal monoatomic gasat pressue P and temperature. T while the other protion is a perfect vacuum. If a hole is opened between the two portion, the change in internal energy of the gas is

A container with insulating walls is divided into two equal parts by a partition fitted with a valve. One part is filled with an ideal gas at a pressure P and temperature T, whereas the other part is completely evacuated . If the valve is suddenly opened, the pressure and temperature of the gas will be

A thermally insulated container is divided into two parts by a screen . In one part , the pressure and temperature are P and T for an ideal gas filled. In the second part it is vacuum. If now a small hole is created in the screen , then the temperature of the gas will

A container contains hydrogen gas at pressure P and temperature T. Another identical container contains helium gas at pressure 2P and temperature T//2 . The ratio of the number of molecules of the two gases is
