The kinetic theory holds that:
 
  a. all matter is composed of tiny particles.
  b. elements combine in fixed proportions to form molecules.
  c. the energy that an object gains as it falls is a result of gravity.
  d. atoms and molecules that make up matter are in constant motion.

Question 2

The energy stored in heating oil is known as which of the following?
 
  a. Elastic c. Chemical
  b. Atomic d. Gravitational

[matt]

Answer to Question 1

ANS: D
Kinetic energy is the energy an object possesses while in motion.

Answer to Question 2

ANS: C
Petroleum reserves of coal, oil, and gas represent chemical potential energy by virtue of the chemical bond that must be broken to release energy. Heating oil potential energy has chemi-cal-to-chemical bonds. Atomic energy involves two processesfission (splitting atoms) and fu-sion (joining two atoms).
