Thermal Energy Transfer Flashcards
(12 cards)
Matter
Something that has mass and takes up space
Energy
The capacity to do something
Kinetic energy
The energy of an object because of motion.
Thermal energy
The total energy of all the moving particles of an object
Temperature
The average kinetic energy of the particles of an object or substance.
Heat
The transfer of energy from warmer places to cooler places due to the difference in temperature.
Conduction
It is the transfer of heat through a solid material by direct contact of particles.
Convection
It is the transfer of heat in a fluid( a gas or liquid ) caused when hotter,less dense fluids rise and cooler, more dense fluids sink.
Radiation
It is the transfer of heat through empty space by invisible electromagnetic rays. No matter is required for the heat transfer to occur.
Thermal Equilibrium
It happens when heat heat flows from a higher temperature object to a lower object until two objects have an equal temperature.
conductor
Insulator
Materials that don’t let heat energy to pass through them well
