KMT is a theory, developed by James C. Maxwell and Ludwig Boltzmann, that predicts the behavior of gases. The theory states that:
· Gases are made of very large numbers of molecules
· Molecules are constantly moving (obeying Newton’s laws of motion), and their speeds are constant
· Molecules are very far apart compared with their diameter
· Molecules collide with each other and walls of container in elastic collisions
· Molecules do not react[1] or exert any other forces (attractive or repulsive) on each other.
ideal gas: a gas that obeys KMT. Most gases are ideal under some conditions (but not all).
