chapter 6 Flashcards
a measure of how hot something is
temperature
an increase in the size of a substance in response to an increase in the temperature
thermal expansion
the temperature at which molecular enery 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 energyas 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 movment 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
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 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
