The force of attraction between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule.

A measure of how compact a substance is, calculated by dividing mass by volume.

The state of a substance when its molecules are closest together and the substance is most compact.

The temperature at which water reaches its maximum density, meaning it's the most compact.

The property of water where its solid form (ice) is less dense than its liquid form.

The tendency of water molecules to stick together due to hydrogen bonding.

The tendency of water molecules to stick to other substances due to hydrogen bonding.

The ability of water to absorb a large amount of heat energy before its temperature rises significantly.

As the temperature of most liquids decreases, their density increases.

The point at which the density of water is the highest, occurring at 4 degrees Celsius.

When water cools below 4 degrees Celsius, it expands, causing its density to decrease.

The process of water transforming from a liquid state to a solid state (ice).

Ice is less dense than liquid water, causing it to float on top of water.

Ice forms at the surface of lakes and ponds, allowing warmer water to remain below and support aquatic life.

A measure of how much mass is contained in a given volume.

The amount of heat energy needed to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Water's unique ability to absorb a lot of heat energy without its temperature changing much. This keeps organisms stable.

Water's ability to absorb large amounts of heat energy without significant temperature changes. This stabilizes lakes and seas.

The amount of heat energy required to convert a liquid to a gas.

Water needs a lot of heat to vaporize due to the strong bonds between its molecules.

A large amount of heat is required to transform liquid water into water vapor. This helps regulate Earth's climate.

The ability of water molecules to stick to each other due to hydrogen bonds. This creates surface tension.

The ability of water molecules to stick to other substances due to hydrogen bonds. This helps water move up plants.

The process where water changes from a liquid to a gas.

Sweating and transpiration help cool down organisms by removing heat energy.

The temperature at which a solid changes into a liquid.

The temperature at which a liquid changes into a gas.

The existence of water as a liquid within a range of temperatures that are common on Earth.

Water is able to dissolve a wide variety of substances. It is called a "universal solvent".

The property of having poles (positive and negative ends) due to uneven sharing of electrons.

Substances that are made of charged particles (ions) and dissolve in water.

Substances where electrons are shared unevenly, creating slightly positive and negative ends.

Water absorbs a lot of heat before its temperature increases significantly.

Water's ability to moderate temperature helps regulate the climate on Earth.
