What state of matter changes state?

Answer 1

a solid → a liquid = melting (heat energy added) e.g. ice melts to water a liquid → a gas = vaporization (heat energy added) e.g. water to water vapour a solid → a gas = sublimation (heat energy added) e.g. dry ice (frozen CO2) to carbon dioxide a gas → a liquid = condensation (heat energy removed) e.g. cloud to rain a liquid → a solid = freezing (heat energy removed) e.g. water freezes to ice a gas → a solid = deposition (heat energy removed) e.g. water vapour to frost * solid-molecules tightly packed definite shape and volume(crystaline structure) * liquid-flow takes shape of container * gas-expands to fill container * plasma-electrons at 5000*C(neon lightning)
