Front

What subatomic particles are found in an atom of phosphorus?

Back

Protons, neutrons, and electrons.

Front

Define cohesion in the context of water molecules.

Back

Cohesion is the property of water that allows molecules to stick to each other, contributing to surface tension.

Front

Define adhesion in the context of water molecules.

Back

Adhesion is the property of water that allows it to stick to other substances, aiding in capillary action.

Front

What is the significance of water's high specific heat?

Back

It helps regulate temperature in organisms and environments, allowing for stable conditions.

Front

What is a solvent?

Back

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

Front

What is dehydration synthesis?

Back

A chemical reaction that involves the removal of a water molecule to form a bond between two molecules.
