Download Solution PDFThe correct answer is Option 2, i.e Alcohol, Petrol, Water, Kerosene oil.
Key Points
- Boiling point and evaporation have an inverse relationship, that is, the higher the boiling point of a substance, the lower is the rate of its transformation from liquid to gas (or evaporation).
- When the particles of a substance (usually a liquid) 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.
- Alcohol has the lowest Boiling Point and hence the highest rate of evaporation, followed by Petrol, Water and Kerosene Oil.
