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 expert.​

Answer 1

Answer:

block" (and any subsequent words) was ignored because we limit queries to 32 words. 

Answer 2

a. Gas molecules have high freedom of movement and low intermolecular attraction so it completely occupies in the vessel as it don't have fixed shape or volume

b. gas molecules are in state of rapid random motion. they collide with walls of container . wall collision account for pressure of gas.

c. a wooden table has fixed size shape and volume as it has high intermolecular attraction and molecules have low freedom of movement it is called as solid .

d. air molecules have a greater intermolecular space the resistance it creates is less. but in case of solid interspace is low and force of attraction is very high only experts can overcome this force so karate expert can juggle easily while a normal can't
