Explain the difference between condensation and evaporation
Answers
Condensation is the change from a vapor to a condensed state (solid or liquid). Evaporation is the change of a liquid to a gas. Microscopic view of a gas. ... Example: Water vapor condenses and forms liquid water (sweat) on the outside of a cold glass or can.
Answer:
Condensation is the change from a vapor to a condensed state (solid or liquid). Evaporation is the change of a liquid to a gas.
The Microscopic View of Condensation
Microscopic view of a gas.Microscopic view after condensation.
When a gas is cooled sufficiently or, in many cases, when the pressure on the gas is increased sufficiently, the forces of attraction between molecules prevent them from moving apart, and the gas condenses to either a liquid or a solid.
Example: Water vapor condenses and forms liquid water (sweat) on the outside of a cold glass or can.Example: Liquid carbon dioxide forms at the high pressure inside a CO2 fire extinguisher.
The Microscopic View of Evaporation
Microscopic view of a liquid.Microscopic view after evaporation.
When a liquid is heated sufficiently or when the pressure on the liquid is decreased sufficiently, the forces of attraction between molecules do not prevent them from moving apart, and the liquid evaporates to a gas.
Example: The sweat on the outside of a cold glass evaporates when the glass warms.Example: Gaseous carbon dioxide is produced when the valve on a CO2 fire extinguisher is opened and the pressure is reduced.
