D. chemical --> thermal --> mechanical

Answers

Answer 1

Answer:

the answer is D. chemical, thermal, and mecanical

Answer 2

The energy transformation occur when propane gas is used to lift a hot air balloon is Chemical-> mechanical-> Light.

What is Propane gas role in hot air balloon?

Propane can be produced from the components of liquid which is recovered during natural gas processing. Also these components include ethane, methane, propane, and butane, as well as heavier hydrocarbons.

The molar mass of propane is C₃H₈ - (12x3) + (1x8)= 44 g/mol.The number of moles of propane present - 0.200 mol1 mol weighs - 44 gMass of propane present  - 8.8 g

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

The chemical propane will be burned at first.All the process in the balloon will be checked and concluded as good mechanism without any leakage.When the propane gas was fired the balloon goes up and its gets lifted with thermal energy.The thermal energy give the Light.

Thus, the process can be simplified as the Chemical energy converting to mechanical energy which later converted to thermal energy and to the Light energy.

Hence, Option B is the correct answer.

Answers

The thermal energy of an object is the energy contained in the motion and vibration of its molecules. Thermal energy is measured through temperature. The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.

Answer:The total kinetic and potential energy of its particles
