Properties of Water and Molecules HMS

Front

What is capillary action?

Back

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces, often observed in plants as water moves through their stems.

Front

What is the universal solvent?

Back

Water is often called the universal solvent because it can dissolve many different substances due to its polar nature.

Front

What percentage of Earth's water is salt water?

Back

97% of Earth's water is salt water.

Front

What happens to molecules in a solid?

Back

Molecules in a solid are tightly packed in a regular pattern. They vibrate but do not move freely.

Front

What is the process of dissolving?

Back

Dissolving is the process where a solute (like lemonade powder) mixes with a solvent (like water) to form a solution.

Front

What is cohesion in water?

Back

Cohesion is the attraction between water molecules, which causes them to stick together, leading to surface tension.

Front

What is adhesion in water?

Back

Adhesion is the attraction between water molecules and other substances, allowing water to climb up surfaces like plant stems.

Front

What is surface tension?

Back

Surface tension is the elastic-like force at the surface of a liquid that makes it behave like a stretched membrane.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solution, such as sugar or lemonade powder in water.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, forming a solution, such as water.
