According to KMT, what are particles in matter always doing?
Moving constantly
Which intermolecular force is the strongest: dispersion, dipole-dipole, or hydrogen bonding?
Hydrogen bonding
According to Charles’ Law, what happens to volume when temperature increases?

Explain why gases are easier to compress than liquids using KMT.
Gas particles are far apart with empty space between them, while liquid particles are close together.
