Chapter 6 Heat and Heat Technology Flashcards
a measure of how hot (or cold) something is; specifically, a measure if 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(0 K on the Kelvin scale or -273.16 degrees Celsius on the Celsius scale
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 the circulation or movement of a liquid or gas
convection
the transfer of energy as electromagnetic waves
radiation
the quantity of heat required to raise a unit mass of homogeneous material 1 K or 1 degrees Celsius in a specified way given constant pressure and volume
specific heat
the physical forms of matter, which include solid, liquid, and gas
state of matter
the change of a 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
