temperature
a measure of how hot something is
thermal expansion
an increase in the size of a substance in response to an increase in temperature
absolute zero
the temperature at which molecular energy is at a minimum
Heat
energy transferred between objects
Thermal Energy
kinetic energy of a substance’s atoms
Thermal Conduction
the transfer of energy as heat through a material
thermal conductor
a material through which energy can be transferred
thermal insulator
a material that reduces the transfer of heat
convection
transfer of thermal energy
radiation
transfer of energy as electromagnetic waves
specific heat
heat required to raise a unit of mass
states of matter
solid, liquid, gas
change of stste
one physical state to another
insulation
a substance that reduces the transfer of eletricity
