types of matter

Question 1

solids

Answer 1

• particles don’t move freely but vibrate
• IMFs hold particles in place
• fixed volume & shape
• not compressible
• crystalline or amorphous particle location

Question 2

crystalline particle formation

Answer 2

repeating 3D structure & fixed pattern

Question 3

amorphous particle formation

Answer 3

particles are disordered & random arrangements

Question 4

liquids

Answer 4

• particles close together
• enough kinetic energy for particles to slide/roll around
• liquids take container’s shape
• not compressible
• solids/liquids of same substance often are similar sizes (cuz particles are close together)
• melting point based on IMFs

Question 5

gases

Answer 5

• particles have enough KE to overcome IMFs holding them together
• particles far apart, moving quickly
• easily compressed (space btwn)
• take container’s shape
• no regular particle arrangement
• frequency/strength of collisions = based on temp, pressure, volume
