Question 14

Kinetic molecular Theory

Answer 14

1. Gas particles consist of large amounts of particles that are far apart from each other relative to their size
2. Gas particles move in continuous, random, straight line motion
3. When particles collide, no energy is gained or lost. Energy is transferred
4. The actual volume of the gas particles is negligible
5. Gas particles do not attract or repel each other.
