I want to know the answer to the following question:
Give one example of energy transformation.
All the background I'm provided with is that "Our Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that in itself (since it still contains the same total energy even if in different forms), but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy.". Is that enough to answer the question?
Answer: no
