Question

An automobile with an internal combustion engine converts the potential energy of gasoline (44 MJ/kg) into the kinetic energy of the moving pistons. If the average internal combustion engine is 10 percent efficient and 1 kg of gasoline is combusted, how much potential energy is converted into energy to run the pistons?

Answer 1

4.4 MJ

Step-by-step explanation:

We are given that an automobile with an internal combustion engine converts the potential energy of gasoline into kinetic energy of the moving piston.

1 kg of gasoline gives energy=44 MJ.

Average internal combustion engine =10 % efficient

We have to find how much potential energy is converted into energy to run the pistons.

10% of 44 =
`(10)/(100)* 44=4.4 MJ`

Since 10% is efficient of internal combustion.

Therefore, 4.4 MJ potential energy is converted into energy to run the pistons.
