Elements.
Explanation:
Modern Chemistry says these are elements.
You don't "turn" it into energy; petroleum HAS stored energy (chemical energy).However, you can turn it into ANOTHER TYPE OF ENERGY; usually this is done by burning the petroleum, and using it to drive machinery.
Since burning fuels is wasteful (the efficiency is limited, in theory, to the Carnot efficiency of a heat engine), other options are being explored, such as chemical reactions in a fuel cell. But such technology is not yet used on a large scale.
Answer: third energy level
Explanation: In a sodium atom, the highest-energy principal energy level containing electrons is the third energy level, and that energy level contains one electron.
Answer:
<u>Potential energy is</u> the stored energy in an object or thing, while <u>kinetic energy is</u> the energy which an object contains because of a particular motion.
