Question

a cfl light bulb turns electrical energy into mostly light and some heat. the production of heat in this energy transformation is most likely caused by which law of thermodynamics? 2nd: in every energy transformation, some energy is lost, usually as heat. 3rd: energy and matter are the same thing. 4th: when energy is used, it disappears forever. 10th: all energy eventually disappears.

Explanation:

The second law of thermodynamics states that in energy transformations, energy is lost (often as heat). A CFL bulb's heat production aligns with this. The third law is about energy - matter equivalence (not relevant here). The fourth and tenth statements are incorrect as energy isn't lost forever (first law: energy is conserved). So, the second law explains the heat production in the CFL bulb's energy transformation.

Answer:

2nd: In every energy transformation, some energy is lost, usually as heat.
