Question

Define what scientists mean when using the term phase changer and provide justification in at least two complete sentences.

Answer 1

A phase change is a physical process in which a substance transitions from one phase to another. Sublimation is the phase change from a solid to a gas, while vaporization is the phase change from a liquid to a gas.

Step-by-step explanation:

A phase change, also known as a phase transition, is a physical process in which a substance transitions from one phase to another. In the case of a phase change from a solid to a gas, it is called sublimation. A phase change is a physical process in which a substance transitions from one phase to another. Sublimation is the phase change from a solid to a gas, while vaporization is the phase change from a liquid to a gas.

An example of sublimation is dry ice (solid carbon dioxide) turning directly into carbon dioxide gas without first becoming a liquid. In the case of a phase change from a liquid to a gas, it is called vaporization. An example of vaporization is water boiling and evaporating to become water vapor.
