Question

question 7. what is energy transformation? a. the process of changing energy from one form to another b. the process of converting energy into matter c. the process of converting matter into energy d. the process of creating energy from nothing

Explanation:

Energy transformation refers to the conversion of energy from one form to another. According to the law of conservation of energy, energy cannot be created or destroyed (eliminating option D). Option B is incorrect as it's about energy - matter conversion which is not the general concept of energy transformation. Option C is about matter - energy conversion (like in nuclear reactions) but not the broad definition of energy transformation. Option A correctly describes energy transformation as changing energy forms (e.g., electrical to mechanical).

Answer:

A. The process of changing energy from one form to another
