9th Science CH6 Using Thermal Energy

TermDefinition
combustion rapid burning
conduction the transfer of energy through matter in which energy moves from particle to particle; conduction takes place more easily in solids than in liquids and gases
convection the transfer of energy by the bulk movement of matter in which particles move from place to place in a fluid, carrying the energy with them
external combustion engine an engine in which the fuel is burned outside the engine; for example, an old-fashioned locomotive steam train
fluid any material that flows; liquids and gases are fluids
heat engine a device that converts thermal energy that is produced by burning fuel into mechanical energy; for example, an automobile engine
heat mover a device that moves thermal energy from one location and releases it in another location having a different temperature
insulator a material that does not allow heat or electrons to move through it easily
internal combustion engine an engine in which fuel is burned inside the engine in chambers (cylinders); for example,an automobile engine
ocean thermal energy conversion process that uses heat engines to convert differences in ocean temperatures into mechanical energy to drive turbines
radiation the transfer of energy in the form of waves; radiation is a type of energy transfer that does not require matter
solar collector a device that absorbs radiant energy from the sun that can be converted to thermal energy used to heat buildings
solar energy energy from the sun; can be converted into thermal energy to heat homes and other buildings
