A chemical substance (H₂O) essential for life; found in oceans, rivers, air, and living things.

A characteristic or quality of a substance that can be observed or measured.

The uneven distribution of electrical charge in a molecule; water has a slightly positive end and a slightly negative end.

Attraction between molecules of the same substance (like water sticking to water).

Attraction between molecules of different substances (like water sticking to glass or plant stems).

The “skin-like” layer on water’s surface caused by strong cohesion between molecules.

Movement of water through small spaces (like plant tubes) due to cohesion and adhesion.

State of matter with a definite shape and volume; particles are tightly packed.

State of matter with definite volume but no fixed shape; flows easily.

State of matter with no definite shape or volume; spreads out to fill space.

Change from liquid to solid when temperature decreases.

Substance that gets dissolved (ex: salt).

Substance that does the dissolving (ex: water).

A mixture where a solute is evenly dissolved in a solvent.

A mixture that looks uniform throughout (same everywhere).

Heterogeneous solution

A mixture where different parts are visible or unevenly mixed.

another name for water because it dissolves many different substances.

Water droplets forming beads on a surface.

Water climbing up a paper towel.

Example of surface tension

A small insect walking on water.

Example of capillary action

Water moving up a plant stem or through soil.

Examples of homogeneous solutions

Saltwater, sugar water, air, vinegar.

Examples of heterogeneous solutions

Salad dressing, muddy water, cereal in milk.

Movement of something (like energy or heat) from one place to another.

The ability to do work or cause change.

Specific heat capacity

Amount of heat needed to change a substance’s temperature; water has a high one.

Transfer of heat through movement of liquids or gases.

The layer of gases surrounding Earth.

All the water on Earth (oceans, rivers, ice, vapor).

Long-term average weather patterns in a region.

Continuous movement of water through evaporation, condensation, precipitation, and collection.

A temperature scale used in science that starts at absolute zero.

A temperature scale based on the lowest possible temperature (no molecular motion).
