Answer:
4.4 MJ
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 =
Since 10% is efficient of internal combustion.
Therefore, 4.4 MJ potential energy is converted into energy to run the pistons.
When water evaporates of your body it cools you down, hence why after a shower when the water droplets begin to evaporate you feel cold
