Master the Interconversion of States of Matter in This Quiz

Changes of State

• When a solid is heated, it changes to a liquid or sublimes (changes directly to a gas) depending on the substance and conditions.
• A gas is the state of matter that completely occupies the space in the container it is placed in.

Heating and Cooling Liquids

• When a liquid is further heated, it changes to a gas (evaporation or vaporization).
• When a liquid is further cooled, it changes to a solid (freezing or solidification).

Phase Changes and Interconvertibility

• The term used to describe the interconvertibility of the three states of matter (solid, liquid, and gas) by changing temperature and pressure is phase change.

Gas and Cooling

• When a gas is cooled, its particles slow down and it may change to a liquid (condensation) or solid (deposition).

Mixtures and their Components

• A substance that contains many types of particles is called a mixture.

Recap of Changes of State

• When a gas is cooled, it may change to a liquid or solid depending on the substance and conditions.
• When a liquid is further heated, it changes to a gas.
• When a solid is heated, it changes to a liquid or sublimes to a gas depending on the substance and conditions.
