The Kinetic Theory explains the effects of temperature and pressure on matter.
The Kinetic Theory makes three assumptions about matter:
Heat IS NOT energy "stored" in matter. Heat exists only as kinetic enery transferred from one system to another.
- All matter is composed of small particles.
- The particles of matter are in constant motion.
- All collisions between the particles of matter are perfectly elastic.
Elastic collisions transfer NO energy between particles. Each particle has exactly the same energy after the collision as before.
This energy can ONLY be transferred from a system that has more of it to a system that has less of it − NEVER the other way around!
Temperature IS NOT the same thing as heat.
This is an example of the Second Law of Thermodynamics that states (in simple terms) "heat cannot spontaneously flow from a colder location to a hotter location".
Explain this true statement: "There is no such thing as cold.
