Properties of Objects and Materials

Properties and Changes of Properties in Matter

A substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of the of the amount of sample.

Water evaporates from the Earth's surface, rises and cools as it moves to higher elevations, condenses as rain or snow, and falls to the surface where it collects in lakes, oceans, soil, and in rocks underground.

• The atmosphere is a mixture of nitrogen, oxygen, and trace gases that include water vapor.
• Clouds, formed by the condensation of water vapor, affect weather and climate.
