SOLIDS TO LIQUID
Heat a solid: particles move more & spread out
Spreading out to much: not a solid anymore
Particles can now slide and glide
Melting: the process of a solid becoming a liquid
Melting point: temp. at which 2 substances melt

3.
SOLID TO GAS
Can directly turn into a gas without becoming a liquid
Requires solid particles to gain a big amount of energy quickly
They require that to increase the kinetic energy
Sublimation: process of going from a solid directly to a gas

LIQUIDS TO GAS
Hot liquid: particles spread out, moving faster
Particles spreading out - not a liquid anymore
Particles now move freely making it a gas
