Key Concepts: Kinetic Molecular Theory

Core Definitions

• KMT Assumption 1: Gas particles are in constant, random, straight-line motion.
• KMT Assumption 2: Gas particles have negligible volume compared to the container.
• KMT Assumption 3: There are no attractive or repulsive forces between gas particles.
• KMT Assumption 4: Collisions between gas particles are perfectly elastic (no energy lost).
• KMT Assumption 5: The average kinetic energy is proportional to absolute temperature (K).
• Ideal Gas: A hypothetical gas that perfectly follows all KMT assumptions.
