Question

How does boiling differ from evaporation? A. Boiling can take place at any temperature, while evaporation takes place at a specific temperature. B. Boiling is a heating process, while evaporation is a cooling process. C. Boiling is a change from a liquid to a gas, while evaporation is a change from a gas to a liquid. D. Boiling takes place throughout a liquid, while evaporation takes place at the surface. Its C isnt it?

Answer 1

Answer: D. Boiling takes place throughout a liquid, while evaporation takes place at the surface.

Explanation: Boiling is a phenomenon in which liquid convert to gaseous state at the boiling temperature of the substance. Evaporation is also a phenomenon in which liquid convert to gaseous state but at any temperature lower than its boiling point.

Boiling is a bulk phenomenon , which means it takes place throughout the liquid whereas evaporation is a surface phenomenon and takes place only at the surface.

Answer 2

Its D :) evaporation happens all the time, and can only occur at the surface (molecules break off and become gases) whereas boiling is when ANY molecule, whether from the surface, the middle or the bottom can just fly off and become a gas.
