Concept 2 Vocabulary: Chemistry of Life

matter

• Water is a polar molecule meaning it has opposite charges on opposite ends. This causes hydrogen bonds to form causing water to stick together.
• Anything that has mass and takes up space
• in a solution, the substance in which the solute dissolves.
• the force that acts on the surface of a liquid and that tends to minimize the area of the surface
