A substance that is made of only one type of atom or molecule, with a uniform and definite composition, and cannot be separated into other types of matter by physical means.

A pure substance that cannot be broken down into simpler substances by chemical reactions.

A pure substance formed when two or more elements combine chemically in a fixed ratio.

A mixture contains two or more substances that are not chemically combined. The substances in a mixture keep their original properties. Mixtures can be separated by physical means.

A homogeneous mixture where one substance (solute) is dissolved in another substance (solvent).

The amount of solute dissolved in a given amount of solvent. It indicates the strength of the solution.

A change in the physical properties of a substance without changing its chemical composition. It's reversible.

A change in the chemical composition of a substance, leading to the formation of a new substance. It's usually irreversible.

Compounds have different properties than the elements that make them up.

Compounds can only be broken down into their constituent elements through chemical processes, not physical ones.

A homogeneous mixture has uniform composition throughout, meaning its components are evenly distributed and not visually distinguishable.

A heterogeneous mixture has non-uniform composition, meaning its components are not evenly distributed and can be visually distinguished.

Homogeneous mixtures have components evenly distributed and cannot be separated by simple physical methods such as filtration.

Heterogeneous mixtures have components unevenly distributed and can be physically separated by methods like filtration.

A type of homogeneous mixture where particles are very small, less than 1 nm, and cannot be separated by filtration. The mixture is transparent and does not scatter light.

A type of homogeneous mixture where particles are larger than in a true solution, between 1-100 nm, and cannot be separated by filtration. The mixture is translucent and scatters light.

A type of heterogeneous mixture where particles are larger than 100 nm and can be separated by filtration. The mixture is opaque and scatters light.

The component that dissolves the other component in a solution.

The component(s) that is/are dissolved in the solvent.

The amount of solute present in a given amount of solution.

The maximum amount of solute that can dissolve in 100 grams of solvent at a specific temperature.

A solution where no additional solute can be dissolved at a specific temperature.

A solution where more solute can be dissolved at a specific temperature.

A solution where particles of a substance are evenly spread throughout.

The substance present in a smaller proportion in a colloid. It's like the solute in a solution.

The substance present in a larger proportion in a colloid. It's like the solvent in a solution.

The scattering of light by colloidal particles, making the beam visible. It's why fog appears white.

A change in the physical properties of a substance without changing its chemical composition. It's often reversible.

Changes in the physical state, size, or shape of a substance are examples of physical changes. These changes are usually reversible by using a physical process.

Substances are converted into entirely new substances during chemical changes. These changes are generally irreversible, meaning they cannot be easily reversed.

Burning a candle is a chemical change, as it involves a reaction with oxygen that creates new substances like carbon dioxide and water. These substances are different from the original wax and cannot be easily turned back.

The Tyndall effect refers to the scattering of light by particles large enough to be seen under a microscope, but not visible to the naked eye. This effect is observed in colloids but not in true solutions.

Pure substances have a fixed composition, they consist of only one type of particle, whether it's an element or a compound. The composition throughout the substance is uniform.

The product, A₂B, in the reaction 2A + B → A₂B, is a compound. It won't show the properties of the original elements, it's a different substance. This reaction is irreversible.
