Heat and Heat Technology Flashcards
A measure of how hot or cold something is
tempature
an increase in the size of a substance in response to an increase in the temperature
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
thermal energy
the transfer of energy as heat through a materal
thermal conduction
a material though 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 of mass of homogeneous material 1 K or 1 C in a specific way given constant pressure and volume
specific heat
the physical forms of matter, which include solid,liquid, or 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
