Exam Success
internal energy - (ANSWER)the sum of the kinetic and potential energies of all particles in the system
Conduction - (ANSWER)The direct transfer of heat from one substance to another substance that it is
touching.
Convection - (ANSWER)The transfer of thermal energy by the circulation or movement of a liquid or gas
convection current - (ANSWER)a current caused by the rising of heated fluid and sinking of cooled fluid
Insulator - (ANSWER)A material that does not allow heat or electrons to move through it easily.
Infra red radiation - (ANSWER)Electromagnetic waves of heat energy.
Radiation - (ANSWER)Energy that is radiated or transmitted in the form of rays or waves or particles.
greenhouse effect - (ANSWER)CO2 and other greenhouse gases in the atmosphere absorb long
wavelength radiation radiated from the Earth's surface and prevent it escaping.
black - (ANSWER)good absorber of radiation
white - (ANSWER)poor absorber of radiation
specific heat capacity - (ANSWER)the energy required to raise the temperature of one gram of a
substance by one degree Celsius
Reduce heat loss from homes - (ANSWER)- loft insulation (fibre glass is a good insulator)
- cavity wall insulation (foam prevents convection currents)
- aluminum foil behind radiator (reflects radiation)
- double glazing (vacuum slows conduction and radiation)
