Joules, kilojoules and megajoules are used to express the amount of energy absorbed or released during a chemical reaction. Think of it this way:
In foods, on the label at the back, there is the amount of kilojoules per xxx grams...
And food is classified as chemical energy, right?
Same concept for other types of energy.
Bilbo Wasn't Just For Burglary, He Was Also Sneaky. Enemies Knew Dwarf Scent Very Well, But A Hobbit Would Be A New Scent. He Was Good For Sneaking Into Places, And When He Had The Ring, That Would Be No Problem.
