Materials

States of Matter

Solid

• Particles in a fixed position
• Particles very close together
• Vibrate
• Uniform particles
• Definite volume
• Do not flow

Liquid

• Particles in a random position
• Particles are close together
• Slide past each other
• No definite shape
• Definite volume
• Cannot compress
• Flows

Gas

• Particles are spread out
• Particles in random position
• Particles move quickly
• Move in all directions
• No definite shape
• No definite volume
• Can be compressed
• Flows

Change of state

Example:

• Ice => Water => Water vapour

<<^^Cold^^<<

• particles get closer together
• losing heat energy

[[Heat[[

• particles get closer together
• more heat energy
