Question

To get the energy equation in terms of temperature, this law is used.

(a) Newton’s third law of motion

(b) Zeroth law of thermodynamics

(c) Fick’s law

(d) Fourier’s law of heat conduction

I had been asked this question by my school teacher while I was bunking the class.

This interesting question is from Energy Equation topic in section Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer 1

Correct answer is (d) Fourier’s law of heat conduction

To elaborate: Fourier’s law of heat conduction gives the relationship between heat energy and temperature. This is used in the energy equation to convert heat terms to temperature terms.
