What is a solid in terms of arrangement, movement and energy of the particles?
Arrangement: Close together, regularly packed
Movement: Vibrate around a fixed point
Energy: Less kinetic energy than liquids and gases
What is a liquid in terms of arrangement, movement and energy of the particles?
Arrangement: Close together, irregular
Movement: Free to move
Energy: More kinetic energy than solids but less than gases
What is a gas in terms of arrangement, movement and energy of the particles?
Arrangement: Far apart, no forces between them
Movement: Free to move
Energy: More kinetic energy than solids or liquids
What are the names of the interconversions?
Melting, Freezing, Boiling, Condensing, Sublimation, Deposition
How is each interconversion achieved?
Melting: Solid is heated
Freezing: Liquid is cooled
Boiling: Liquid is heated
Condensing: Gas is cooled
Sublimation: Low air pressure and heating
What is diffusion?
The random motion of particles from an area of high concentration to an area of low concentration
What is dilution?

What is the definition of solvent?
The liquid in which a substance dissolves
What is the definition of solute?
The substance that is dissolved
What is the definition of solution?
The liquid formed when a solute dissolves in a solvent
What is the definition of a saturated solution?
