The correct expression of partial pressure in terms of mole fraction is :

The pressure of a $$1 : 4$$ mixture of dihydrogen and dioxygen enclosed in a vessel is one atmosphere. What would be the partial pressure of dioxygen?

Dipole-dipole forces act between the molecules possessing permanent dipole. Ends of dipoles possess 'partial charges'. The partial charge is:

According to kinetic theory of gases, the collisions between molecules of a gas:

The kinetic theory of matter helped a great deal in understanding the behaviour of gases. Which of the following statements did not belong to it?

Which scientist discovered that the same amount of space was occupied by equal numbers of molecules of gases, irrespective of whether it was hydrogen or chlorine or fluorine?

Which of the following assumptions is incorrect according to kinetic theory of gases?

Which of the following is correct?

Equal masses of helium and oxygen are mixed in a container at $$25^{\circ}C$$. The fraction of the total pressure exerted by oxygen in the mixture of gases is :

As the temperature increases, average kinetic energy of molecules increases. What would be the effect of increase of temperature on pressure provided the volume is constant?
