How is the energy of the universe conserved during the combustion of gasoline in a car engine?

The energy produced during combustion of gasoline in a car engine is converted as kinetic energy.

Explanation

The conservation of energy clearly states that "energy can neither be created nor be destroyed , it can only be transferred from one form to another form".

The combustion of gasoline in a car engine tends to generate heat energy, this heat energy will be transferred as kinetic energy which will lead to motion of cars.

This the energy of the universe will be conserved as the energy created by the combustion is used as kinetic energy for movement of cars.

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
