Rate of evaporation is______(a) directly proportional to temperature of liquid(b) inversely proportional to temperature of liquid(c) independent of temperature of liquid(d) directly proportional to humidity of surrounding airI got this question in an online interview.Query is from Evaporator topic in section Building Blocks of Dairy Processing of Dairy Engineering

Answer»

Correct answer is (a) directly proportional to temperature of LIQUID

To EXPLAIN I would SAY: Evaporation depends directly on temperature of liquid. Higher the temperature of the substance the GREATER is the kinetic energy of the molecules at its surface and therefore the faster the RATE of their evaporation.
