Chapter 6 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 modular energy is at a minimum (0 K on the Kelvin scale or -273.16 on the Celsius scale)
absolute zero
teh energy transferred between objects that are different temperatures
heat
the kinetic energy of a substance’s atoms
thermal energy
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 the circulation or movement of a liquid or gas
convection
the transfer of energy as electromagnetic waves
radiation
the quantity
specific heat
the physical forms of matter which include solid, liquid, and gas
states of matter
the change of a substance from one physical state tp another
change of state
a substance that reduces the transfer of electricity, heat, or sound
insulation
a machine that transforms heat energy into mechanical energy
heat engine
a temperature increase in a body of water that is caused by human activity and that has a harmful effect on water quality
thermal pollution
