Answers & Comments
Answer:
Evaporation is a phase transition from the liquid phase to the gas phase that occurs at temperatures below the boiling point at a given pressure.
For molecules of a liquid to evaporate, they must be located near the surface, be moving in the proper direction, and have sufficient kinetic energy to overcome liquid-phase intermolecular forces.
Boiling is a phase transition from the liquid phase to the gas phase that occurs at or above the boiling temperature.
Boiling is the rapid vaporization of a liquid and occurs when a liquid is heated to its boiling point. A liquid’s boiling point is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environment (air).
Key Terms
Vaporization: Vaporization is a phase transition from the liquid phase to the gas phase.
manometer: An instrument to measure pressure in a fluid, especially a double-legged liquid column gauge used to measure the difference in the pressures of two fluids.
Boiling: Boiling is the rapid vaporization of a liquid and occurs when a liquid is heated to its boiling point, or the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the surface of the liquid by the surrounding atmospheric gas (air).
Evaporation: A type of vaporization of a liquid that only occurs on the liquid’s surface.
