Explain why gases can be compressed

Here are the answers to your questions:

1) Describe the movement of particles in gases.

Particles in gases move randomly and rapidly in all directions. They travel in straight lines until they collide with other gas particles or the walls of their container. These collisions are elastic, meaning kinetic energy is conserved.

2) Explain why gases can be compressed.

Gases can be compressed because there are large empty spaces between their particles. When pressure is applied, these particles are forced closer together, significantly reducing the overall volume of the gas.
