6th CK HEAT AND ENERGY TRANSFER A - C SET 1 - COMPLETE

TermDefinition
Absolute zero the temperature at which no more energy can be removed from matter.
Amorphous Solid the particles are not arranged in any particular order
Biomass Material in growing or dead plants.
Boiling point the temperature at which a liquid boils.
Calorie amount of heat required to raise the temperature of one gram of water one degree Celsius.
Calorimeter a device that measures changes in thermal energy
Celsius scale the temperature scale on which zero and 100 are the temperatures at which water freezes and boils.
Change-of-state a change from one state (solid or liquid or gas) to another without a change in chemical composition.
Chemical Change one or more substances break apart or combine to form a new substance
Chemical Energy potential energy stored in chemical bonds that hold chemical compounds together; for example, wood, wax, and food such as chocolate and broccoli store this
Chernobyl A place in Ukraine where a nuclear power plant – a generator powered by a nuclear reactor – underwent a meltdown in 1986.
Combustion Burning; a chemical reaction that involves the rapid combination of a fuel with oxygen to produce thermal energy.
Condensation the change from the gaseous to the liquid form of matter.
Conduction flow of heat energy from one molecule to the next; warmer particles passing some of their warmth onto cooler particles without the movement of matter itself.
Conductor a material that easily transfers heat between its particles.
Contraction when a substance loses heat energy, the molecules slow down, and the substance contracts to become smaller in size
Convection flow of energy/transfer of that that occurs when warm liquid or gas rises; particles move taking their heat with them
Convection current a current caused by the rising of heated fluid and sinking of cooled fluid.
Crystalline Solid the particles form regular, repeating patterns
