The first law of thermodynamics states that _____.
A) in a perfect engine all of the heat is converted to mechanical work
B) torque is a measure of work
C) resistance is work that results from burning fuel
D) energy cannot be created or destroyed

Question

Quizplus · Accepted Answer

The first law of thermodynamics, also known as the law of conservation of energy, states that energy cannot be created or destroyed, only transformed from one form to another. Therefore, energy is always conserved. Option A is incorrect as a perfect engine is a theoretical concept that does not exist in reality. Option B is incorrect as torque is a measure of rotational force, not work. Option C is incorrect as resistance is a measure of opposition to the flow of electric current, not work resulting from burning fuel.
