Condensation
Condensation is the process by which a gas or vapor changes into a liquid. This occurs when the temperature of the gas decreases, causing the particles to slow down and come closer together, eventually forming a liquid.
Factors Affecting Condensation
- Temperature: Lowering the temperature of a gas or vapor increases the likelihood of condensation.
- Pressure: Increasing the pressure can also lead to condensation, as it forces the gas particles closer together.
- Surface Area: A larger surface area provides more places for condensation to occur, such as the inside of a glass of cold water.
- Presence of Nuclei: Condensation is more likely to occur in the presence of particles or nuclei for the water vapor to condense onto.
Examples of Condensation
Condensation can be observed in various natural phenomena and everyday experiences, including:
- Dew forming on the grass in the early morning
- Cloud formation in the atmosphere
- Steam turning into water droplets on a mirror in a bathroom
Study Guide
When studying condensation, be sure to understand the molecular changes that occur when a gas transitions to a liquid. Pay attention to the role of temperature, pressure, and surface area in influencing condensation. Practice identifying examples of condensation in the environment and how it relates to the water cycle. Additionally, familiarize yourself with the different forms of condensation, such as dew, fog, and cloud formation.
