Ch.6 Heat and Heat Technology Flashcards
a measure of how hot (or cold) something is’ specifically, a measure of the average kinetic energy of the particles in an object
temperature
an increase in the size of a substance in response to an increase in the temperature of the substance
thermal expansion
the temperature at which molecular energy is at a minimum
absolute zero
the energy transferred between objects that are at different temperatures
heat
the kinetic energy of a substance’s atoms
thermal energy
the transfer of energy as heat through a material
thermal conduction
a material through which energy can be transferred as heat
thermal conductor
a material that reduces or prevents the transfer of heat
thermal insulator
the transfer of thermal energy by circulation or movement of a liquid or gas
convection
the physical forms of matter, which include solid, liquid, and gas
states of matter
the change of substance from one physical state to another
change of state
a substance that reduces the transfer of electricity, heat, or sound
insulation
a machine that transforms heat into mechanical energy, or work
heat engine
a temperature increase in a body of water that’s caused by human activity and that has a harmful effect on water quality and on the ability of that body of water to support life
thermal pollution
the transfer of energy as electromagnetic waves
radiation
