Question

What is the kinetic energy of a gas?

Answer 1

1. According to the kinetic theory of gases, a gas is made up of identical point particles.
2. These particles are in a constant state of random motion and do not interact with each other.
3. Due to the constant motion of the particles, they undergo elastic collision.
4. Like any other classical particle, these gas particles follow Newton's laws of motion and their kinetic energy is proportional to the mass and the square of the velocity of the particle.
5. For a gas, the average kinetic energy per particle (molecule) is directly proportional to the temperature of the gas.
6. The average kinetic energy per unit volume of a gas is also directly proportional to the pressure of the gas.
