Thermal Energy Lesson 1 How is thermal energy transferred
Measure of kinetic energy of molecules Thermometer Fahrenheit Celsius Kelvin TEMPERATURE
Total kinetic and  potential energy in a substance. Thermal energy determines how warm a substance feels. Warm water has more thermal energy than cool water. Thermal Energy
Thermal energy always moves from warmer to cooler objects. Heat is the result of molecules vibrating quickly. Heat is moving energy. HEAT
The transfer of heat by direct contact between objects or particles. During conduction the particles in substances do not move, energy is passed as the particles vibrate and bump against  one another. Conduction
Heat transferred through space as waves EXAMPLE:  The sun’s rays causing a sunburn. Radiation
Heat transferred by the movement of molecules within a substance. Movement occurs from warmer areas to cooler areas. Convection
The movement of a substance that is caused by differences in temperature and density. EXAMPLES:  wind  boiling water NATURE WANTS  EVERYTHING TO BALANCE ! !  Convection Current
Conductors are materials that transfer heat easily. Examples: metals like copper and gold Conductors
An insulator is a material that does not transfer heat easily.  Examples:  liquids and gases A jacket Insulators
