Question

The first law of thermodynamics is derived from which of the following law ?

• A. the law of conservation of energy
• B. the law of specific heat
• C. the ideal gas law
• D. the law of entropy
• E. the law of conservation of temperature

Answer 1

The correct option is A the law of conservation of energy

According to 1st law of thermodynamics, $Q=\Delta U+W$

$⟹$ Energy can neither be created nor be destroyed.

Thus 1st law of thermodynamics is derived from law of conservation of energy.
