Independent variable
A variable we change
Dependent variable
A variable we measure
Control variable

Properties of a solid
Regular pattern
Tightly packed
Vibrate in fixed position
Dont loose shape
Held by very strong forces
Cant be compressed
Properties of a liquid
Particles are close
Held by strong forces
Slide and move
No shape
Take the shape of the container
Irregular pattern
Cant be compressed
Properties of a gas
Spread apart
Very weak forces
Move quickly and more randomly
Can be compressed
No shape or volume
Solid to liquid
Melting
Liquid to solid
Freezing
Liquid to gas
Evaporation or vaporisation
Gas to liquid
Condensation
Solid to gas
Sublimation
Gas to solid
Deposition
Why does a solid expand on heating
A solid expands on heating as the particles gain kinetic energy and start to vibrate more and as they do their binds weaken
What will happen if you keep on heating it
The particles will keep on drifting away as the force of attraction will decrease until the solid turns into a liquid
