Which description best matches this particle model?

• Particles are closely packed, vibrate fixed position, strong intermolecular forces.
• Particles are closely packed, no movement, strong intermolecular forces
• Particles are closely packed, move around each other, medium intermolecular forces

Which description best matches this particle model?

• Particles are closely packed, randomove around each other, strong/medium intermolecular forces
• Particles are loosely packed, move around each other, strong/medium intermolecular forces
• Particles are closely packed, move randomly around each other and have weak intermolecular forces.

Which description best matches this particle model?

• Particles move fast in specific directions, weak intermolecular force
• Particles have a lot of space between them and move fast in random directions.
• Particles have lots of energy and have a medium intermolecular forces between them. 

Which state of matter can be compressed?

• Solid
• Liquid 
• Gas

Which is the correct formula?

• density = mass x volume
• mass = volume x density
• volume = density x mass
