8. The diagram below shows a hot air balloon rising. Propane gas tanks are seen at the bottom of the balloon
What energy transformations occur when propane gas is used to lift the balloon?
A. thermal-> Chemical-> light
B. Chemical-> mechanical->
Thermal
C. Chemical-> mechanical-> thermal
D. Mechanical-> light-> Chemical

C. Chemical-> mechanical-> thermal

Explanation:

The energy conversion for the propane, that is, energy transformations that occur when propane gas is used to lift the balloon will be:

Chemical energy converting to mechanical energy which later converted to thermal energy

The correct option is therefore Chemical-> mechanical-> thermal which is option C
