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

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
