Grade.8 Science Heat/Light Unit

HeatA form of energy caused by internal motion of molecules of motion
MoleculesTiny particles of matter that is always in motion
Heat TransferMovement of heat from a warmer object to a cooler one
ConductionHeat transfered through a substance or from one substance to another by direct contact of molecules
ConvectionHeat transfer in liquids and gases by means of convection currents
RadiationHeat transfer through space.
Kinetic EnergyEnergy that a moving object has due to its motion; energy of motion.
TemperatureMeasure of the motion of molecules.
ThermometerInstrument used to measure temperature.
Celcius ScaleMetric temperature scale on which water freezes at 0 and boils at 100.
Kelvin ScaleMetric temperature scale on which O.K repersents absolute zero, the freezing point of water is 273 K , and the boiling point of water is 373 K.
Absolute ZeroTemperature at which all molecular motion cases; lowest possible temperature (O.K -237"c).
CaloriesUnit used to measure heat.
Specific HeatAbility of a substance to absorb heat energy.
CalorimeterInstrument used to measure the heat given off in chemical reactions.
Potential EnergyEnergy stored in a substance.
Phase ChangeChange of matter from one phase (solid, Liquid, or gas) to another.
Heat Of FusionAmount of heat needed to change a substance from the solid phase to the liquid phase.
Heat Of VaporationAmount of haet needed to change a substance from the liquid phase to the gas phase.
Regular ReflectionBouncing back of light from a smooth, even surface.
Diffuse ReflectionBouncing back of light from an uneven surface.
Plane MirrorMirror with a perfecly flat surface.
Concave MirrorMirror with a surface that curves inwards.
Convex MirrorMirror with a surface that curves outwards.
Convex LensLens that is thicker in the middle than at the edges.
Concave LensLens that is thicker at the ends than in the middle.
TranslucentMaterial that transmits light but no detail.
OpaqueMaterial that does not transmit light.
Polorized LightLight in whtich all the waves are vibrating in the same directions.
PupilOpening in the center of the eye through which light enters.
IrisColoured area surrounding the pupil that controls the amount of light entering the light.
