Particle model of matter

Particle model

Density - The quality of mass per unit volume in a substance.

D = M/V

Density is measured in Kg/M cubed or g/cm cubed

States

Solids

• Closely pack particles
• Regular arrangement of particles 
• Vibrate, no movement

Liquid

• Closely pact together
• Irregular arrangement of particles
• random movement in the liquid 

Gas

• Lose particles 
• Irregular arrangement of paticles
• random sporadic movement in gas

State changes

• Solid -> Liquid = melting
• Solid -> Gas = sublimation
• Liquid -> solid = freezing
• liquid -> Gas = evaportation
• Gas ->…
