Heat Transfer I
The transfer of energy through space by means of rays or waves; energy transmitted by electromagnetic waves.
What is radiation?
This is the sum of a system's kinetic and potential energy.
What is mechanical energy?
An apple is an example of this kind of energy.
What is chemical energy?
This is a type of heat transfer that involves the direct contact between two objects, and is found in liquids and gases.
What is conduction.
A light bulb turns this electrical energy into this kind of energy.
What is radiant?
What is the total potential and kinetic energy
of particles in an object.
What is thermal energy
The sun, a light bulb, and an X-ray all use this type of energy.
What is radiant energy?
This is the type of potential energy found in a compressed spring.
What is elastic energy?
The flow of energy from a warmer to a cooler object. Also called thermal energy.
What is Heat.
Your body uses this kind of energy from your food and turns it into motion and heat.
What is chemical?
The measure of the amount of heat energy a substance has.
What is temperature.
This type of energy is caused by vibrations, travels in waves, and is sensed by us through our ears.
What is sound?
This is the energy of motion.
What is kinetic energy?
Molecules move from warm to cold until they reach a balanced temperature.
What is Thermal Equilibrium
A windmill turns wind into this type of energy.
What is electrical?
As molecules are cooled they move closer together and cause objects to shrink (contract). Cooling = Smaller
What is Contraction.
A thermometer measures this kind of energy.
What is thermal energy?
The movement of gases or liquids caused by differences in density from heating and cooling.
What is convection.
A toaster turns this kind of energy into this kind of energy.
What is electrical energy into thermal energy?
As molecules are heated they spread out as they move around quickly and cause objects to become larger (expand). The expansion of matter caused by heating. Heating = Bigger in Size
What is Expansion.
If you imagine a drop of water about to fall down a waterfall, at the top of the waterfall the drop of water has this kind of energy.
What is potential energy?
This is stored energy.
What is potential energy?
What is an example of a convection current?
The Great Conveyor Belt, warm and cold air masses.
This kind of energy is given off in every energy transfer.
What is thermal energy?
