When electricity is produced from coal, the chemical energy in coal is first changed to what type of energy?
See below.
Burning coal releases two types of energy: thermic energy, or heat, and luminous energy, or light. The heat is used to bring a liquid to a boil, while the luminous energy is wasted.
This heated liquid turns into a gas and begins to ascend (kinetic energy - movement), pushing a fan positioned at an angle along the way.
Magnets are moved by this fan, and when the magnetic field changes, current is created, converting the kinetic energy of the movement into electric energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
