Condensation: Explanation
Condensation is the process by which a gas or vapor changes into a liquid. This occurs when the temperature of the gas or vapor decreases, causing the molecules to lose energy and come closer together, eventually forming a liquid. Condensation is the opposite of vaporization, where a liquid changes into a gas. This process is crucial in the water cycle, where water vapor in the atmosphere condenses to form clouds and eventually precipitation.
Condensation: Study Guide
- Understanding the Process: Familiarize yourself with the concept of condensation and how it differs from vaporization. Understand the role of temperature in causing condensation.
- Factors Affecting Condensation: Study the factors that influence condensation, such as temperature, pressure, and the presence of nuclei for condensation to occur.
- Applications of Condensation: Explore the real-world applications of condensation, such as in the formation of clouds, the operation of refrigeration systems, and the distillation of liquids.
- Condensation in the Water Cycle: Gain an in-depth understanding of how condensation plays a crucial role in the water cycle, leading to the formation of clouds, fog, and precipitation.
- Experiments and Demonstrations: Engage in experiments or demonstrations that illustrate the process of condensation, such as creating a cloud in a bottle or observing condensation on a cold surface.
- Problem-Solving: Practice solving problems related to condensation, such as calculating the amount of water vapor that can condense at a certain temperature and pressure.
- Connection to Other Concepts: Connect the concept of condensation to other related topics in chemistry, such as phase changes, thermodynamics, and the behavior of gases.

Physical Science
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
