✯✯ QUESTION ✯✯

Give Reason :

A.gas fills completely the vessel in Which it is kept..

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

✰✰ ANSWER ✰✰

The particles of gas have high kinetic Energy and they move in all possible directions independent of each other because there is no force of attraction between them..Therefore a gas fills completely in which it is kept..

Some properties of Gas : -

☛Gases do not have definite shape and volume..

☛Gases have high compressibility.

☛Gases have low densities.

☛Gases have high rate of diffusion..

☛Gases flow independently in all the directions at high speed..

Answer 2

Answer:

the explanation is behind the kinetic theory of gases

• the forces of attraction between the atoms of gas is negiligible , so particles move away easily . in solids force of attraction is high (ex ionic) so particles cannot move away from each other.
• the collision between particles is elastic so they does not lose energy and always in random motion.
• particles move in 3 dimension so they acquire all space of closed vessel.
