A $$1.00$$L vessel containing $$1.00$$ g $$H_2$$ gas at $$27^0$$C is connected to a $$2.00$$ L vessel containing $$88.0$$g $$CO_2$$ gas, at also $$27^0$$C. When the gases are completely mixed, total pressure is:

A vessel contains 0.5 mole each of $${ SO }_{ 2 }{ ,H }_{ 2 }$$ and $$CH_{ 4 }$$. Its outlet was made open and closed after sometime. Thus, order of partial pressure will be:

An ideal gas obeying kinetic gas equation :

The vapour pressure of pure $$A$$ is $$10$$ torr and at the same temperature when $$1\ g$$ of $$B$$ is dissolved in $$20\ gm$$ of $$A$$, its vapour pressure is reduced to $$9.0$$ torr. If the molecular mass of $$A$$ is $$200$$ amu, then the molecular mass of $$B$$ is:

A balloon filled with methane $$CH_4$$ is pricked with a sharp point and quickly plunged into a tank of hydrogen at the same pressure. After sometime the balloon will have?

At a pressure of 760 torr and temperature of 273.15K, the indicated volume of which system is not consistent with the observation?

The volume of helium gas is 44.8 L at:

How much should the pressure be increased in order to decrease the volume of a gas by $$15\%$$ at a constant temperature?

A gaseous mixture contain 1 gm of $${ H }_{ 2},$$ 4 gm of $$He$$ 7gm of $${ N }_{ 2 } $$ and 8gm of $${ O }_{ 2 }$$. The gas having the highest partial pressure is:

An aquatic species need at least 4mg/L of $$O_{2}$$ for their survival. $$O_{2}$$ in water at 273K and 1 atm pressure is $$2.21 \times 10^{-3}$$ mol/L. The partial pressure of $$O_{2}$$ above water(in an atmosphere at 273K) needed for the survival of species is:
