Questions and Answers
What are the properties of a solid, liquid, gas, vapor, and plasma?
A solid has its own definite shape and volume. A liquid flows, has constant volume, and takes the shape of its container. A gas flows to conform to the shape of its container and fills the entire volume. A vapor refers to the gaseous state of a substance that is a solid or a liquid at room temperature. A plasma results when the particles of a gas become ionized and are broken apart into smaller charged particles.
What are extensive and intensive properties of matter?
Extensive properties, such as mass, length, and volume, are dependent on the amount of substance present. Intensive properties, such as density, are independent of the amount of substance present.
What is a physical property of matter?
A physical property is a characteristic of matter that can be observed or measured without changing the sample’s composition.

Study Notes
States of Matter
- A solid has a fixed shape and volume, with particles closely packed and vibrating in place.
- A liquid has a fixed volume but takes the shape of its container, with particles close together but able to slide past each other.
- A gas has neither a fixed shape nor volume, with particles widely spaced and free to move rapidly.
- A vapor is a type of gas that is below its critical temperature, and can be liquefied by compression or cooling.
- A plasma is a high-energy state of matter, where atoms are ionized and electrons are free to move about.
Properties of Matter
- Extensive properties depend on the amount of matter, such as mass, volume, and energy.
- Intensive properties do not depend on the amount of matter, such as density, temperature, and color.
Physical Properties of Matter
- A physical property is a characteristic of a substance that can be observed or measured without changing its composition.
- Examples of physical properties include melting point, boiling point, density, and solubility.
Physical Change in Matter
- A physical change is a change in which the substance remains the same but its physical properties change.
- Examples of physical changes include melting, freezing, condensation, and evaporation.
Chemical Change in Matter
- A chemical change is a change in which the substance transforms into a new substance with a different composition.
- Examples of chemical changes include combustion, rusting, and decomposition.
