States of Matter
These particles are packed tightly together in a fixed shape.
What is a solid?
This type of property can be observed without changing the substance into something new.
What is a physical property?
Tearing a piece of paper is an example of this type of change, because no new substance is formed.
What is a physical change?
Matter is classified as pure substances and mixtures. Elements and compounds both fall under this broader category.
What are pure substances?
This is a combination of two or more substances where each substance keeps its own properties.
What is a mixture?
This state of matter has a definite volume but no definite shape.
What is a liquid?
Flammability and reactivity are examples of this type of property that describes how a substance can change into a new substance.
What is a chemical property?
Rust forming on iron is an example of this type of change that involves the reaction of a metal with oxygen.
What is a chemical change?
Oxygen, gold, and iron are all examples of this type of substance that appears on the periodic table.
What is an element?
A salad, trail mix, or sand and iron filings are examples of this type of mixture, where the components are not evenly distributed.
What is a heterogeneous mixture?
This state of matter spreads out to completely fill its container.
What is a gas?
This type of property is shared by both intensive and extensive categories, depending on whether it depends on the amount of matter.
What is a physical property?
A color change, production of gas, or formation of a precipitate are all possible signs of this type of change.
What is a chemical change?
Water, carbon dioxide, and sodium chloride are all examples of this type of pure substance made from two or more elements chemically combined.
What is a compound?
Salt dissolved in water forms this type of mixture, also known as a solution, where the components are evenly distributed.
What is a homogeneous mixture?
Evaporation is when this state of matter changes into a gas.
What is a liquid?
Density and color are examples of this type of property that does not depend on the amount of substance present.
What is an intensive property?
Sublimation, when dry ice turns directly into gas, is this type of change because no new substance is formed.
What is a physical change?
This simplest form of matter cannot be broken down into smaller substances by chemical means.
What is an element?
This separation technique is often used to separate pigments in ink or plant leaves.
What is chromatography?
This state of matter is made of charged particles with very high energy, often found in lighting.
What is plasma?
Mass and volume are examples of this type of property that changes when the amount of substance changes.
What is an extensive property?
This scientific law states that matter cannot be created or destroyed in a chemical reaction.
What is the law of conservation of mass?
This type of pure substance can be broken down into simpler substances by chemical means, but not by physical means.
What is a compound?
This separation method uses a funnel and paper to separate solid particles from a liquid.
What is filtration?
