THERMAL ENERGY TRANSFER Flashcards
science
Matter
Anything that takes up space and has mass.
States of matter
Solid, liquid, gas
Energy
The capacity to do work or cause change.
Kinetic Energy
The energy of an object because of motion. The word ‘kinetic’ stems from the Greek word for motion.
Thermal energy
The total energy of all of the moving particles in an object.
Temperature
Measures the average kinetic energy of the particles of an object or substance. It is like a speedometer for how fast particles are moving.
Heat
The heat of the energy from your hand or something that’s hot.
Conduction
When you place your hand onto a soda your energy is transferred to the soda and then your hand is transferred from the soda to your hand.
Convection
The Transfer of heat in a
Fluid ( A gas or a Liquid) Caused when hotter, less dense fluid rise, and cooler, more Dense sink.
Radiation
Thee Transfer of heat through empty space by invisible electromagnetic rays. No matter is required for the heat transfer to occur.
Thermal Equilibriunm
Heat flows from a higher temperature object to a lower temperature object until the two objects have an equal temperature.
Conductor
Materials that allow heat energy to move through them efficiently are called conductors. The particles in good conductors are typically close together (dense), like in metals.
Insulator
Materials that don’t allow heat energy to pass through them well are called insulators. People use insulators to keep heat in or to keep out. Feathers, wool, and rubber are good insulators.
