Respuesta :

Liquid gold is poured into molds and cools to become solid bars. The gold is "FREEZING"

Liquid nitrogen becomes a gas when it is poured out of its container. The nitrogen is "BOILING"

Solid iron is heated to high temperatures so that it becomes a liquid. The iron is "MELTING"

Water vapor in the air becomes tiny liquid droplets that form fog. The water is "CONDENSING'

In a very cold cryogenic freezer, solid oxygen forms on the walls from the oxygen gas in the air. The oxygen is "DEPOSITING"

In the high desert, snow changes to water vapor without becoming liquid water. The snow is "SUBLIMING"

The gold is frozen. The nitrogen is vaporized. The iron is melted. The water is condensed. The oxygen is deposited. The snow is sublimed.

Phase changes are physical changes, in which matter changes from one state to another. Each phase change has its own name.

Let's identify each of the phase changes described below.

  • Liquid gold is poured into molds and cools to become solid bars. The gold is frozen (Freezing is the passage from liquid to solid).
  • Liquid nitrogen becomes a gas when it is poured out of its container. The nitrogen is vaporized (Vaporization is the passage from liquid to gas).
  • Solid iron is heated to high temperatures so that it becomes a liquid. The iron is melted (Melting is the passage from solid to liquid).
  • Water vapor in the air becomes tiny liquid droplets that form fog. The water is condensed (Condensation is the passage from gas to liquid).
  • In a very cold cryogenic freezer, solid oxygen forms on the walls from the oxygen gas in the air. The oxygen is deposited (Deposition is the passage from gas to solid).
  • In the high desert, snow changes to water vapor without becoming liquid water. The snow is sublimed (Sublimation is the passage from solid to gas).

The gold is frozen. The nitrogen is vaporized. The iron is melted. The water is condensed. The oxygen is deposited. The snow is sublimed.
