1. Petroleum is called “buried sunshine” because the energy it contains originated from the sun.
2. Types of Energy:
a. Potential energy is energy that is stored up and ready for use; it is also referred to energy of position. Example: a car at the top of a hill.
b. Kinetic energy is energy associated with the motion of an object. Example: a bouncing ball.
3. During a chemical reaction, bonds are either destroyed or formed.
4. Butane has more potential energy because it has more atoms, therefore more energy to give off.
5. Kinetic or potential:
a. Potential
b. Potential
c. Kinetic
d. Potential
e. Kinetic
6. Energy is required because it takes force to pull apart the bonds, or to remove the electrons.
7. Endothermic or Exothermic:
a. Exothermic
b. Endothermic
c. Exothermic
8. There is more energy in the gases and heat given off, then the energy needed to break the bonds within the candlewick.
9. On paper
10. Energy is neither created nor destroyed in any mechanical, physical, or chemical process.
