the process that changes a substance from a liquid to a gas below the substance’s boiling point
a gas law that states that the volume of a gas is directly proportional to its temperature
the phase change in which a substance changes directly from a gas to a solid
the state in which matter has both a definite shape and a definite volume
the phase change in which a substance changes from a gas to a liquid
the phase change in which a substance changes directly from a solid to a gas
the type of phase change in which a substance releases energy to its surroundings
the type of phase change in which a substance absorbs energy from its surroundings

Explanation:

1. The process that changes a substance from a liquid to a gas below the substance's boiling - point is evaporation.
2. A gas law that states that the volume of a gas is directly proportional to its temperature is Charles's law.
3. The phase change in which a substance changes directly from a gas to a solid is deposition.
4. The state in which matter has both a definite shape and a definite volume is solid.
5. The phase change in which a substance changes from a gas to a liquid is condensation.
6. The phase change in which a substance changes directly from a solid to a gas is sublimation.
7. The type of phase change in which a substance releases energy to its surroundings is exothermic.
8. The type of phase change in which a substance absorbs energy from its surroundings is endothermic.

Assuming the circled letters spell out the hidden term, we need to identify those letters from the above - mentioned words.

Answer:

Hidden Term: States of Matter
Definition: The different forms in which matter can exist, including solid, liquid, and gas, and the phase changes between them such as evaporation, condensation, sublimation, and deposition.
