Question

Quizplus · Accepted Answer

The first law of thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed, but it can be changed from one form to another (such as from chemical energy to thermal energy). This statement is accurately represented in option A. Option B is incorrect as it suggests that one form of energy cannot be converted into another, which is not true. Option C is incorrect as it suggests complete conversion between certain types of energy, which is not always possible. Options D and E are partially correct but do not provide a complete explanation of the first law.
