Solids Liquids + Gases

Question 1

Solid

Answer 1

Particles packed together tightly and are constantly vibrating in place.
Particles are bonded together in a regular pattern, slowly vibrating.
Fixed volume and shape
Incompressible

Question 2

Liquid

Answer 2

Particles are packed tightly but move slightly more freely. More KE and EPE.
Particles can slip and slide past one another.
Fixed volume. Flow to change shape.
Incompressible.

Question 3

Gas

Answer 3

Particles are far apart => small attractive forces between them. Most KE and EPE.
Particles can move far apart
No fixed volume or shape.
Highly compressible.
