Question

Which of the following is not the assumption of kinetic theory of gases

Answer 1

The simplest kinetic model is based on the assumptions that: (1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size; (2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the

Answer 2

The kinetic-molecular theory does not assume that all gas particles in a sample have the same velocity.

Explanation:

• Gas particles have a hard time compressing at high pressures.
• The kinetic theory of gases makes no such assumption.
• The low-pressure scenario is mentioned in the postulates of the kinetic theory of gases, but the high-pressure example isn't included.

Kinetic energy:

• If the pressure of the gas remains constant, the volume (V) of a given mass of gas is directly proportional to the temperature of the gas.
• A gas, according to the kinetic theory, is made up of a huge number of submicroscopic particles (atoms or molecules) all moving at random.
• The fast-moving particles collide with one another and with the container's walls on a regular basis.
