Question

Which of the following example does not explain conduction?

(a) The heat from a hot liquid makes the cup itself hot

(b) Walking on the beach on a hot summer day will warm the feet

(c) A metal spoon becomes hot from the boiling water inside the pot

(d) The formation of sea and land breeze

This question was posed to me during an internship interview.

My question is from Heat Conduction topic in portion Heat Transfer Theory of Food Processing Unit Operations

Answer 1

Right choice is (d) The formation of sea and land breeze

To explain I would say: The formation of sea and land breeze is an example of convection. The other examples are due to conduction where transfer of heat in internal energy by minute collision of particles and electron movement within a body.
