Science-states of matter

Solid

Particles closely packed, vibrate in place, strong attraction, least energy

Liquid

Particles close but disordered, slide past each other, moderate energy

Gas

Particles far apart, fast random motion, weak attraction, most energy

Melting

Solid heated; particles vibrate faster, move apart, solid → liquid

Boiling

Liquid heated; particles gain energy, overcome attraction, liquid → gas

Freezing

Liquid cooled; particles lose energy, slow down, solidify

Condensation

Gas cooled; particles lose energy, slow down, become liquid

Sublimation

Solid → gas without becoming liquid

Deposition

Gas → solid without becoming liquid

Diffusion

Net movement of particles from high to low concentration
