Study Notes
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.
