Transfer Of Energy As Heat Flashcards
Energy moves heat in three ways
• Conduction
•Convection
• Radiation
The transfer of thermal energy with no transfer of matter, from a region of higher temperature to a region of lower temperature and acts to equalize temperature differences.
CONDUCTION
It requires direct contact or particle -to-particle transfer of energy; usually occurs in solids
CONDUCTION
The process that moves energy from one object to another when they are touching physically.
Conduction
: materials that transfer energy easily.
Conductors
: materials that do not transfer energy easily.
Insulators
The transfer of thermal energy when particles of a liquid or gas move from one place to another
Convection
Heat moves in currents; hot air rises and cold air falls;
only occurs in fluids.
Convection
in the earth and sun
Convection
The circular flow of hot and cold creates convection currents
Convection
The transfer of thermal energy by waves moving through space.
Radiation
radiate energy!
ALL OBJECTS
The energy that travels by electromagnetic waves (visible light, microwaves, and infrared light)
Convection
