Question

At constant volume for a gas the pressure of the gas increases with rise in temperature due to

Answer 1

Explanation:

the pressure of the gas increases because with the increase in temperature, energy gets added to its molecules.

the speed with which the molecules move increases as a result of this energy addition,

but since the volume is constant, they have to move in the same space as before resulting in an increased energy exchange due to collisions with the vessel walls and with themselves.

thus, there is a increase in pressure.

The collision of the particles with the walls of the vessels give rise to the pressure of the gas.
