Question

3. Give reasons (a) A gas fills completely the vessel in which it is kept. (b) A gas exerts pressure on the walls of the container, (c) A wooden table should be called a solid. (d) We can easily move our hand in air but to do the same through a solid block of wood we need a karate exper? ​

Answer 1

Explanation:

a) Because they have low force of attraction so they move in random manner and hence fill the vessel completely.

b) They have high kinetic energy so they move in with random manner and hence they exert a force on wall of container.

c) • They have strong molecular force of attraction

• They have definite shape

•They have definite volume

Hence it is a solid

d) Because air particle have very low force of attraction while solid block has high attraction force.
