Evaporation and Boiling Quiz

How is evaporation different from boiling?

• Evaporation is spontaneous and occurs at any temperature.

• Boiling is spontaneous and occurs at any temperature.

• Evaporation requires a specific temperature.

• Boiling is a cooling process.

What is the difference and similarity between evaporation and boiling?

• Both are gaseous phases.

• Both depend on vapor pressure.

• Evaporation is a cooling process while boiling is a heating process.

• Boiling is fast while evaporation is slow.

Example of boiling and evaporation?

• Water converted into vapor phase during hot summer.

• Water boils at a specific temperature which is 100oC.

Which is the slower process, evaporation or boiling?

• Evaporation

• Boiling

Why is it that water evaporates off of any warm surface despite its boiling point being 100 oC?

• Because of evaporation which occurs at any temperature.

• Because boiling takes place at the temperature of 100oC.

How to make water evaporate fast?

What is the difference between drying and evaporation?

• Drying means the complete removal of water.

• Evaporation is the conversion of liquid into vapor phase spontaneously.

What is the difference between evaporation and crystallization?

• Crystallization is a process in which crystals are formed.

• Evaporation is the change of a liquid into the gaseous phase.

What is the difference between boiling and sublimation?

• Sublimation is the conversion of a solid into a gaseous phase without into a liquid phase.

• Boiling is a temperature at which internal pressure becomes equal to external pressure.

When water evaporates, does its mass decrease?

• Yes, the mass of water decreases.

• No, the mass of water remains the same.
