Kinetic Molecular Theory (KMT) of Gases

• Postulate 1: Particles of gas are in constant motion and collide with both one another and the container.
• Postulate 2: The gas is mostly empty space.
• Postulate 3: Pressure is exerted when the particles hit the sides of the container.
• Postulate 4: We assume that the particles do not interact with each other.
• Postulate 5: Average kinetic energy is proportional to the temperature.
