|
Kinetic Energy
|
The energy an object has because of its
motion
|
|
Kinetic theory
|
All matter consists of tiny particles that are
in constant motion
|
|
Kinetic theory assumptions
|
1.) particles- very small, insignificant volume, hard spheres
2.) motion- quickly, random, constantly moving
3.) collision- elastic, inelastic
|
|
Elastic Collision
|
Tennis balls, pool balls
|
|
Inelastic collision
|
Car, train crash (stick together)
|
|
Vacuum
|
Empty space with no particles and no pressure
|
|
Conversion Factors
|
1 atm = 760 mmHg = 101.3 kPa
|
|
How are kinetic energy and temperature related?
|
When there is heat, particles have more movement, kinetic energy increases.
|
|
Intermolecular forces
|
Forces of attraction between molecules
|
|
Vaporization
|
The conversion of a liquid to a gas or vapor
|
|
Evaporation
|
Occur at surface of liquid
|
|
Vapor pressure
|
Water molecules get trapped, vapor pressure is pressure above the liquid
|
