Answer :
The speed of molecules in a gas varies inversely with molar mass of the gas and is inversely related to temperature.
What happens to the particles of gas if put in high temperature?
Gases have fast-moving particles that regularly collide with one another and the container's side as they move quickly in all directions. The particles gain kinetic energy and accelerate with an increase in temperature. A gas molecule therefore moves at an average speed of 500 m/sec. The speed of sound in a gas is approximately 340 m/s.
Therefore, there is a relationship between the average kinetic energy of the gas molecules and its temperature. The average kinetic energy of gas particles remains constant when a gas is compressed without affecting its temperature. Although the container is smaller, the particles still move at the same speed. Particles move quicker from one end of the container to the other as a result.
