I have been asked this question in semester exam.

I'd like to ask this question from Energy Equation topic in portion Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer 1

The correct option is (b) Both the left-hand side and the right-hand side of the equation change

For explanation: Changes are applied to only left-hand side terms in the equations, but they affect both the left and right-hand sides of the equation.
