Question

spiral light bulbs are known to be energy efficient, what evidence did you observe that supports that claim? (select all that apply)
they produce very little thermal energy
they produce a lot of thermal energy
they produce light energy without as much thermal energy
they dont get as hot

Explanation:

Energy efficiency in bulbs means converting more input energy to light (useful) and less to heat (wasted). Spiral bulbs (e.g., CFLs) waste little thermal energy, produce light with minimal heat, and don’t get as hot—all observable evidence of efficiency. Producing a lot of thermal energy is inefficient.

Answer:

they produce very little thermal energy, they produce light energy without as much thermal energy, they don’t get as hot
