Question

what happens to particle motion if the temperature of the gas is increased

Answer 1

The particles of a gas move rapidly and can spread separated from each other. The particles of a fluid can move past each other.

At the point when the temperature is expanded, the particles will move all the more quickly and the normal kinetic energy of the molecules additionally increases.

The heat can be utilized to accelerate the atoms of the substance. Since Kelvin temperature is straightforwardly relative to the normal kinetic energy of particles in a substance, a favor increment temperature causes an equivalent factor increment the normal kinetic energy of the atoms.

Answer 2

According to kinetic theory of matter, matter is made up of particles called atoms or molecules which are in continuous motion.
In gases , the particles are very loosely packed and they have very weak force of attraction.
The gas particles have high K.E .
As the temperature increases, heat energy inside the system increases and gas particles gain this heat energy and increase their kinetic energy and The particles starts diffusing faster.
Since temperature is a measure of average kinetic energy of particles.
