Thermal Energy
Heat energy
Temperature
Measure of average kinetic energy in a material
Heat
The movement of thermal energy from a region of higher temperature to a region of lower temperature
Conduction
The transfer of thermal energy via direct contact
Convention
The transfer of thermal energy via movement of particles from one area to another
Convention current
The movement of fluids in a cycle caused by convection
Solid
-definite shape
-definite volume
-compact
-slow
-low energy
-vibration
-High attraction
Liquid
-Definite volume
-No definite shape
-More loose
-Faster than a solid
-more energy than a solid
-medium attraction
Gas
-No definite shape
-No definite volume
-very spread apart
-drifting around the space they occupy
-fastest of all three states
-little to no attraction
Viscosity
A measurement of a liquid’s resistance to flow
Surface Tension
The uneven forces acting on the particles on the surface of the liquid
Vapor
The gas state of a substance that is normally a solid or liquid at room temperature
Kinetic Energy
Energy in motion
Potential energy
Stored energy
Vaporization
The change in state from liquid to gas
Evaporation
A slow process taking place at the surface of a liquid (liquid to gas)
Condensation
The change in state from gas to liquid
Sublimation
Solid to gas
Deposition
Gas to solid
Melting
Solid to liquid
Freezing
Liquid to solid
Kinetic Molecular Theory
An explanation of how water particles behave
Pressure
The amount of force per unit area applied to an object’s surface
Charles’s Law
Volume increasing, constant pressure, increasing temperature
