states of matter

Question 1

cohesion

Answer 1

the tendency of particles of the same kind to stick together

Question 2

Solid

Answer 2

• particles are packed closely together
• fixed shape and volume
• lowest amount of energy

Question 3

Liquid

Answer 3

• particles move
• takes shape of the container
• fixed volume, but not shape
• more energy than solids

Question 4

Gas

Answer 4

• weakest cohesive force
• particles move more freely than liquids
