According to the law of conservation of energy, when a car uses 10,000 J of chemical energy from gasoline, how much of this energy will be transformed into mechanical, sound, or heat energy?PLEASE HELP
A. 5000 J
B. 2500 J
C. 10,000 J
D. 20,000 J

Respuesta :

It will be C. 10,000

The correct answer to the question is C).10,000 J.

EXPLANATION:

Before going to answer this question, first we have to understand 'Law of conservation of energy'.

The law of conservation of energy states that energy can neither be created nor be destroyed. It can only change from one form to another form, and the total energy of the universe is always constant.

As per the question, the car uses 10,000 J of chemical energy from gasoline.

The energy derived from gasoline will be converted into mechanical energy, sound, heat energy respectively.

The sum of the mechanical,sound and heat energy will be equal to the initial chemical energy; otherwise, it will violate the fundamental law of conservation of energy which is a universal truth.

Hence, the total amount of energy transformed into mechanical,sound and heat energy is 10,000 J.
