States Of Matter and Interconversions (state changes)

Question 0

Liquid

Answer 0

Particles can move slowly, take shape of container, cannot be squashed, particles touching, irregular pattern

Question 1

Solid

Answer 1

Fixed position, shape eg. block, particles cannot be squashed, particles VIBRATE, particles touching, pattern/regular particle formation

Question 2

Gas

Answer 2

Particles move very fast, can be squashed, no fixed shape - always fill container, particles spread out (not touching)

Question 3

Melting

Answer 3

Solid-liquid

Particles heat up and begin to move around a little more, still touching

Question 4

Freezing

Answer 4

Liquid-solid

Particles cool down, causing them to have less energy and slow down until they can only vibrate

Question 5

Evaporation

Answer 5

Liquid-gas: some particles on surface gain enough energy to escape (from sun)

Question 6

Boiling

Answer 6

Liquid-gas: heated up giving ALL particles enough energy to escape (separates molecules NOT atoms)

Question 7

Condensation

Answer 7

Gas-liquid

The particles are cooled so they lose energy and slow down until they form liquid

Question 8

Sublimation

Answer 8

Solid-gas: rare eg. dry ice (CO2), iodine (I), ammodium chloride
Particles are rapidly heated and flake off solid as gas
