Common Gases that Condense:
* Water Vapor (H2O): This is the most familiar example, as it condenses into liquid water (rain, dew, etc.).
* Carbon Dioxide (CO2): Condenses into a solid (dry ice) at atmospheric pressure.
* Nitrogen (N2): The main component of air, condenses into a liquid at very low temperatures.
* Oxygen (O2): Also a major component of air, condenses into a liquid at very low temperatures.
* Argon (Ar): A noble gas, condenses into a liquid at very low temperatures.
* Helium (He): The only gas that cannot be solidified by increasing pressure alone, it can be condensed into a liquid at extremely low temperatures.
Factors Affecting Condensation:
* Temperature: Gases condense when the temperature drops below their condensation point (or boiling point).
* Pressure: Increasing pressure can also force a gas to condense.
Other Gases that Condense:
Many other gases, including methane, propane, ammonia, and various hydrocarbons, can condense under appropriate conditions of temperature and pressure.
Important Note:
It's important to remember that the term "gas" is often used loosely. Some substances are technically gases at room temperature and pressure, but they readily condense into liquids or solids even at slightly lower temperatures.
