Explanation:
The Question is to Identify each of the phase changes described.
Liquid gold is poured into molds and cools to become solid bars.
Phase Change -> Solidification
Liquid nitrogen becomes a gas when it is poured out of its container.
Phase Change -> Vapourization
Solid iron is heated to high temperatures so that it becomes a liquid.
Phase Change -> Melting
Water vapor in the air becomes tiny liquid droplets that form fog.
Phase Change -> Vapourization
In a very cold cryogenic freezer, solid oxygen forms on the walls from the oxygen gas in the air.
Phase Change --> Deposition
In the high desert, snow changes to water vapor without becoming liquid water.
Phase Change --> Sublimation
