Question

Which statement is true according to the kinetic theory?

Answer 1

c.Solids have a fixed shape, so they do not show random motion of particles.

Answer 2

Answer:

The correct answer is option (a).

Explanation:

The very first postulate of kinetic gas theory discuss that the gases have a random motion of particles. The motion of the gas particles continues in a straight lines until or unless they get collide with another particles or with the walls of the containers.

Whereas as other postulates were:

• Gas particles are of point masses with no volume.
• No molecular forces are at work.
• Gas pressure is due to collision of particles with walls of container.
• Kinetic energy of the gas particles is measured in Kelvin temperature.
• Lighter particles moves with higher speed than heavier gas particles.
