Explain the process of deposition and provide an example of it.

What phase transition occurs when a liquid turns into a solid by lowering its temperature below the freezing point?

Describe the process of melting and what causes it to occur.

What is the term for the phase transition in which a gas changes directly into a solid without becoming a liquid first?

What is the process by which water vapor changes directly to ice without becoming a liquid?

Define sublimation and provide an example.

Explain the term 'vaporization' and its relationship with liquid phase.

What is the reverse process of condensation?

Describe the phase transition that occurs during freezing.

Changes of States of Matter

Matter can change from one state to another when thermal energy is released or absorbed.

Phase Transitions

Freezing: a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point.
Melting: a phase transition in which a substance changes from a solid to a liquid when its internal energy increases, typically by the application of heat or pressure.
Deposition: a phase transition in which gas transforms into solid without passing through the liquid phase, and is also known as desublimation.
Sublimation: a phase transition in which a substance changes directly from the solid to the gas phase, without passing through the intermediate liquid phase.
Vaporization: a phase transition from the liquid phase to vapor.
Condensation: the change of the physical state of matter from gas phase into liquid phase, and is the reverse of vaporization.

Examples of Deposition

Snow forms in clouds when water vapor changes directly to ice without first becoming a liquid.
Frost and hoar frost form on the ground or other surfaces when water vapor changes directly to ice without first becoming a liquid.

Vapor Pressure

Liquids are continuously vaporizing, and a partial pressure of the vapor state builds up in a closed vessel with space above it.
Vapor pressure of a liquid is the partial pressure of the vapor over the liquid, measured at equilibrium at a given temperature.
Vapor pressure of a liquid is the equilibrium pressure of a vapor above its liquid (or solid).
