Explanation:
The kinetic energy of a gas molecule is given by :
[tex]E=\dfrac{3}{2}kT\\\\\implies E\propto T[/tex]
It means, whenever the temperature of gas is increased, its kinetic energy will increase and the space between the particles gets increase. So, the space in which particles can collide with each other increases i.e. its volume gets high.
Hence, the correct option is (A). "higher temperature more kinetic energy → more space between particles – higher volume".
