Considering quantity, the largest amount of energy transformation in the world takes place from which of the following?
Think it through first, then pick an option.
- a electrical energy
- b chemical energy
- c light energy
- d heat energy
Answer and explanation
Correct answer: d heat energy
The book says that by quantity the most energy transformation happens from heat energy (in every engine heat turns into mechanical energy).
Why the other options are wrong
- a electrical energy: This is not the answer: The book says that by quantity the most energy transformation happens from heat energy (in every engine heat turns into mechanical energy).
- b chemical energy: This is not the answer: The book says that by quantity the most energy transformation happens from heat energy (in every engine heat turns into mechanical energy).
- c light energy: This is not the answer: The book says that by quantity the most energy transformation happens from heat energy (in every engine heat turns into mechanical energy).
