Answer:
E
Explanation:
From the law of conservation of energy, energy can neither be created nor destroyed but can be converted from one form to another. The kind of energy in fuels can be said to be chemical energy. This chemical energy in fuel is good enough to do some work by its conversion process to other forms of energy. It is the end of the last amount of this conversion that brings us to the term that the fuel is exhausted and we need to refuel so as to be able to do more work of conversion.
The chemical energy in fuels is usually converted to heat energy in cylinders which can then be converted to make the vehicle move from one point to another with a continuous conversion of this fuel.

Answer:
1370moles
Explanation:
Given parameters:
Number of molecules in methane = 8.25 x 10²⁶molecules
Unknown:
Number of moles of methane = ?
Solution:
A mole of any substance contains the Avogadro's number of particles which is 6.02 x 10²³molecules;
6.02 x 10²³ molecules is contained in 1 mole of a substance
8.25 x 10²⁶molecules of methane will contain
= 1370moles
Pool smell is due, not to chlorine, but to chloramines, chemical compounds that build up in pool water when it is improperly treated. Chloramines result from the combination of two ingredients: (a) chlorine disinfectants and (b) perspiration, oils and urine that enter pools on the bodies of swimmers.
