Question

Is conduction faster than convection?

(a) True

(b) False

This question was posed to me in a job interview.

I'd like to ask this question from Heat Convection in section Heat Transfer Theory of Food Processing Unit Operations

Answer 1

Right answer is (b) False

The explanation is: Convection is faster than conduction. In convection the medium in which heat transfer takes place is in motion whereas the heat transfer through conduction takes place by collision between the atoms.
