Thermal Energy Transfer Flashcards
(13 cards)
Matter
anything that takes up space and has weight
States of matter
Solid, liquid, gas, and plasma
Energy
heat, light, electrical energy, or mechanical energy
Kinetic energy
The energy of an object because of motion
Temperature
The average kinetic energy of the particles of an object or substance.
Heat
The flow of energy from warmer places to cooler places due to difference in temperature.
Conduction
The transfer of heat through a solid material by direct contact of particles.
Convention
The transfer of heat in a (a gas or liquid) caused when hotter less dense fluids rise and cooler, more dense fluids sink
Radiation
The transfer of heat through empty space by invisible electromagnetic rays
Thermal equilibrium
it happens when heat flows from a higher temperature object to a lower temperature object until the two objects have equal temperature.
Conductor
Materials that allow electrical current to flow through them easily.
Insulator
a substance which does not really allow the passage of heat or sound
Thermal energy
The total energy of all the moving particles of an object
