Chapter 9 Science Flashcards
a measure of hot hot or cold something is
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 minimum
absolute value
the energy transferred between objects that are different temperatures
heat
the kinetic energy of a substances atoms
thermal energy
the transfer of energy as heat through metal
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*C in pressure and volume
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
