Phase change.
physical change
The point at which a liquid becomes a gas is the boiling point. The point at which a gas becomes a liquid is still called the boiling point. A solid going straight to gas without passing through a liquid state is called sublimation. Dry Ice solid CO2 is a substance that that sublimes.
Both! The physical state of a substance can go straight from gas to solid, or can heat from solid to liquid and then to gas. The process a solid undertakes when it goes straight to its gas state from a solid state without first turning liquid is called sublimation.
Solid, liquid, gas, or plasma. A substance can occur in any one these states. All matter occurs in one of these 4 states. These are the 4 states of matter.
Liquid to a solid is: freezingLiquid to a gas is: condensationSolid to a liquid : is meltingGas to a liquid is: evaporation
condensation
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
condensation
A change from gas to liquid, from solid to liquid, from liquid to gas, etc.
Evaporation, which is a phase change.
liquid changes to gas through the process of evaporation. then when a gas changes back into a liquid it goes through the process of condensation
A liquid or gas that can pass through something
condensation
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
Sublimation - the process by which a substance goes directly from the solid to the gaseous state without passing through the liquid state.
Solid--->Liquid---->Gas
Solid--->Liquid---->Gas
temperature goes up when gas is forced to change into a liquid. The amount the temperature goes up is related to the "heat of vaporization" of the particular substance.
