(b) First law of thermodynamics

(c) Second law of thermodynamics

(d) Kirchoff’s law

The question was posed to me in a job interview.

I want to ask this question from Convective Mass Transfer topic in chapter Mass Transfer of Bioprocess Engineering

Answer 1

Right option is (c) Second law of thermodynamics

Explanation: Second Law of Thermodynamics states that It is not possible for heat to flow from a colder body to a warmer body without any work having been done to accomplish this flow. Energy will not flow spontaneously from a low temperature object to a higher temperature object.
