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 : What is the change in the temperature of the gas ?

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 : What is the change in internal energy of the gas ?

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 : What is the final pressure of the gas in A and B ?

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

A cylinder with a movable piston contains3moles of hydrogen atstandard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume ?

Two separate bulbs contain ideal gas A and B . The density of a gas A is twice that of a gas B . The molecular mass of A is half that of gas B . The two gases are at the same temperature. The ratio of the pressure of A to that gas B is

Consider two containers A and B containing identical gases at the same pressure, volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original value adiabatically. The ratio of final pressure of gas in B to that of gas in A is

Two closed vessels of equal volume containing air at pressure P_(1) and temperature T_(1) are connected to each other through a narrow tube. If the temperature in one of the vessels is now maintained at T_(1) and that in the other at T_(2) , what will be the pressure in the vessels?

Two vessels connected by a valve of negligible volume. One container (I) has 2.8 g of N_(2) at temperature T_(1) (K) . The other container (II) is completely evacuated. The container (I) is heated to T_(2)(K) while container (II) is maintained at T_(2)//3(K) . volume of vessel (I) is half that of vessel (II). If the valve is opened then what is the mass ratio of N_(2) is both vessel (W_(I)//W_(II)) ?

Initially bulb "a" contained oxygen gas at 27^(@)C and 950 mm of Hg and bulb "B" contained neon gas at 27^(@)C and 900 mm of Hg. These bulbs are connected by a narrow tube of negligible volume equipped with a stopcock and gases were allowed to mix-up freely. The pressure obtained in the combined system was found to be 910 mm of Hg. If volume of bulb B was measured to be 10 L, then find the volume of oxygen gas present initially in bulb "A" .
