a) States Of Matter

Arrangement, movement and energy of particles in solids?

Regular arrangement.

Vibrate about a fixed positIon.

Low kinetic energy.

Arrangement, movement and energy of particles for liquids?

Randomly arranged.

Move around each other.

More kinetic energy than solids.

Arrangement, movement and energy of particles for gases?

Randomly arranged.

Move quickly in all directions.

High kinetic energy.

Interconversion of solid and liquid?

Solid to liquid = melting

Liquids to solid = freezing

Interconversion of liquid and gas?

Liquids to gas = boiling

Gas to liquid = condensing

Interconversion of gas and solid?

Gas to liquid = desublimation/deposition.

Liquids to gas = sublimation

Changes in particles when changing from solid to liquid to gas?

Particles gain more kinetic energy.

Move around more freely.

More randomly arranged and further apart.

Changes in particles when changing from gas to liquid to solid?

Particles lose kinetic energy.

Move less.

More regularly arranges and closer together.

Define diffusion?

Movement of particles from area of high concentration to area of low concentration.

Results of diffusion of gases?

Gas diffuses into air.

Particles move randomly.

Gas’s molecules are further apart so colour is paler.

Results of dilution of solid?

Solid dissolves in water.

Particles in liquid move freely.

Allows solid’s particles to be less concentrated so colour is paler.

Define solvent?

The liquid in which a solute dissolves in.

Define solute?

The substance which dissolves in a liquid.

Define solution?

The mixture formed when a solute is dissolves in a solvent.

Define saturated solution?

A solution with the maximum concentration of solute dissolved in the solvent.
