Question

Prove that working is good for health through first law of thermodynamics

Answer 1

The first law of thermodynamics is the application of the conservation of energy principle to heat and thermodynamic processes: The first law makes use of the key concepts of internal energy, heat, and system work. It is used extensively in the discussion of heat engines.

First of all, the first law of thermodynamics IS refutable. Like every other SCIENTIFIC statement/hypothesis/theory, it has to be FALSIFIABLE. Falsifiability is the possibility to prove the theory to be false. Without it, a theory is "not right, and not even wrong" (Wolfgang Pauli).

Answer 2

Proving that the "working is good for health" through "first law of thermodynamics":

• According to the "1st law of thermodynamics", "energy can neither be created" "nor destroyed in the system".
• When we do some external mechanical work, energy is used up in the process.
• The chemical and the physical processes which lead to the "evolution or absorption of heat", part of that might be converted into a work.
• Thus, the "energy of the system" is conserved in correlation to the 1st law of thermodynamics. Energy only depends on "initial and final" states.
