Question

how will you show that the process of evaporation depends on the nature of liquid

Answer 1

take two jars one containing kerosene oil in one jar and simple water in second jar
keep them in sunlight
notice them time to time after 10 minutes
we will observe that kerosene oil will evaporate fast than water.

Answer 2

Answer:

1) Take 10ml of ether (a low boiling point liquid with boiling point 34°C) in a test tube and 10ml of water(boiling point 100°C) in another test tube. keep both the test tube near the window for some time. It is observed that ether evaporates in a shorter time .Thus, lower the boiling point of the liquid,higher is its rate of evaporation.
