Answer 1

Answer:

MARK MY ANSWER AS BRAINLIEST PLEASE

Explanation:

B.The pressure exerted by a gas is due to the random motion of particles in thegas. Gases have weak intermolecular forces and the particles in continuous random motion and these particles collide with the walls of the container. These collisions with the walls of the container exerts pressure on the gas.

C.It is very rigid and cannot be compressed, i.e., it has a solid characteristic. There is a strong force of attraction between molecules of wood, and intermolecular space is the least.

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. It is because the molecules of air has less force of attraction between them and a very small external force can separate them.
