During a movie night at Avery's house, Henry and William were curious about how the energy transfers on the T.V. they were watching. Can you explain it to them??

• The sun shines on the T.V., converting solar energy to light energy, which then turns into thermal energy.

• The T.V. uses nuclear energy, which is then converted to electricity.

• The T.V. uses electricity, which is then converted to solar energy and finally to mechanical energy.

• The T.V. uses electrical energy, which is then converted to light and sound energy.
