Which of the Following Statements is Contrary to the First

Question

Which of the following statements is contrary to the first law of thermodynamics?
A) When energy is used, it is irreplaceable.
B) Matter can be converted into energy.
C) The amount of energy in the universe is constant.
D) Energy can be converted from one form to another.
E) Energy can be transferred from one form to another.

Accepted Answer

The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed in an isolated system. Options B, C, D, and E are consistent with this principle, as they allude to the conversion and conservation of energy. However, option A is contrary to the first law because it suggests that used energy is irreplaceable, implying that energy can be destroyed or lost, which contradicts the law's assertion that the total energy is conserved.
