What is phase change?

Phase change refers to the process in which a substance transitions from one physical state to another, such as from a solid to a liquid or from a liquid to a gas. This transformation occurs as a result of changes in temperature and pressure, causing the molecules of the substance to rearrange themselves and shift between different states of matter.

What are the different phases of matter?

The different phases of matter are solid, liquid, gas, and plasma. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, gases have neither a fixed shape nor volume and fill the entire space available to them, while plasmas are ionized gases with free-flowing electrons and positively charged ions.

What is the process called when a substance changes from a solid to a liquid?

The process where a substance changes from a solid to a liquid is called melting.

What is the name of the process when a substance changes from a liquid to a gas?

The process when a substance changes from a liquid to a gas is called "vaporization" or "evaporation".

When a gas changes directly into a solid without first becoming a liquid, what is this process called?

The process of a gas changing directly into a solid without first becoming a liquid is called deposition.

What is the temperature at which a substance changes from a solid to a liquid called?

The temperature at which a substance changes from a solid to a liquid is called the melting point.

What is the temperature at which a substance changes from a liquid to a gas called?

The temperature at which a substance changes from a liquid to a gas is called the boiling point.

What is the process called when a substance changes from a gas to a liquid?

The process called when a substance changes from a gas to a liquid is known as condensation.

What is the process called when a substance changes directly from a gas to a solid without first becoming a liquid?

The process is called deposition, where a substance changes directly from a gas to a solid without passing through the liquid state.

What is the term used to describe the amount of heat energy required to change the phase of a substance?

The term used to describe the amount of heat energy required to change the phase of a substance is called the heat of fusion or heat of vaporization, depending on whether the substance is changing from a solid to a liquid or from a liquid to a gas, respectively.
