• connecting energy
• electrostatic energy
• gravitational energy

When particles collide with each other they...

• transfer kinetic energy
• stop completely still
• become smaller
• lose all their energy

• solid, liquid and gas
• on and off
• a mystery

Density is a measure of...

• mass in a given volume
• distance in a given volume
• distance in a given time
• speed in a given distance

Two cubes have identical volume, but one has a higher density.  It is...

• heavier
• lighter
• softer
• rougher

Particles in a solid are tightly bound and...

• do not change relative position
• flow down a slope
• float in the air
• are runny

Particles in a liquid are loosely bound, can change their relative position and hence...

• flow into the shape of their container
• will never move
• have zero energy
• are always hot

Between collisions with other particles and their container, gas particles...

• travel fast in straight lines
• do not move at all
• travel in ever decreasing spirals
• have no energy

We cannot compress most solids and liquids, but a gas...

• can be compressed
• is not a state of matter
• makes an excellent chair
• is always heavier than a solid
