Question

Is the energy spent on thinking or talking a
kind of work? Give reason for your answer.​

Answer 1

No. Energy is undoubtedly spent in thinking and in work, but if we have to take physical expediture of energy, there should be some force applied and some displacement covered in order to define that action as "work" and calculate energy from it.

Answer 2

Answer:

Yes

Explanation:

To answer this question we need to know what work is.Work is the process of energy transfer to the motion of an object via application of a force.So,when we talk,our vocal chords are vibrating and hence sound energy is produced.The same happens while we are thinking, complex cells in our brains transfer information and these cells interact with each other.
