As we learnt in

Kinetic Theory of Gases -

Average kinetic energy of the gas molecules is directly proportional to the absolute temperature.

 

-

 

 PV=\frac{1}{3}mn\ V_{rms}^{2}=\frac{2}{3}\times \frac{1}{2}mn\ V_{rms}^{2}=\frac{2}{3}kT

(1)    Boyle's Law: At constant temperature average kinetic energy is constant so Vrms remains unchanged. If volume increases pressure of gas decreases.

i.e. PV = constant.

2.    Charle's Law: If we allow the volume to change to maintain constant pressure the volume will increase with increasing temperature.

V = K T

3.    Avogadro's Law: Under similar condition of pressure and temperature, equal volume of all gases contain equal number of molecules.

V\alpha\ n

Correct option is 4.
