Question

How is evaporation rate determined by boiling point?

Answer 1

⭕️ Boiling is a point in a particular substance is the condition during which the vapor pressure of the liquid becomes equal to the it’s surrounding pressure.

∴ during boiling liquid transform into liquid and the point at which this occurs is called as "boiling point".

 ⭕️ Evaporation is defined as vaporization of a liquid where vapor pressure exceeds its surrounding pressure and liquid phase of substance changes to gaseous phase.

⇒Example- Boiling of water do not change its phase where as evaporation means change of phase of water into gas phase!!!!!!!!!!!!!!!

Answer 2

Answer:

Boiling point and evaporation have an inverse relationship, the higher the boiling point of a substance, the lower is the rate of its Evaporation.

When the particles of a substance is heated up, its particles absorb the energy provided thereby increasing their kinetic energy resulting to more movement of the individual particles. There comes a period when the violent vibrations created breaks their bonds with other particles.
