Assertion : Gases exert pressure on the walls of the container.
Reason: The inter molecular force of attraction is very strong in gases
Answers
Answer:
Assertion is correct but the Reason is incorrect.
Explanation:
A gas exerts pressure on the walls of the container. Reason: They have high kinetic energy and negligible force of attraction to move constantly moving with high speed in all directions. These collisions of the gas particles with the container walls exert pressure on the walls of the container.
(a) The particles of gases have a low force of attraction between them. The particles are freely moving in the vessel in which it is filled.
(b) The particles of gas have the least force of attraction. They are constantly moving randomly. The particle of gas hits the walls of the container thereby applying force and hence pressure on the wall.
(c) The wooden table has a definite shape and a definite volume. The particles of wood are closely packed. They do not take the shape of the container. Hence wooden table satisfies the properties of solid.
(d) The particles of air are very loosely bounded. They are far away from each other having a lot of space between them. Hence we can easily move our hands in the air. But in a solid block, the particles are tightly held by a strong force of attraction. So there is some or no space between them. Hence we need a karate expert.
