chapter 6 Flashcards
temperature
a measure of how hot (or cold) something is;specifically, a measure of the average of the average kinetic energy of the particles in an object.
thermal expansion
an increase in the size of a substance in response to an increase in the temperature of the substance.
absolute zero
the temperature at which molecular energy is at minium
heat
the energy transferred between objects that are at different temperatures
thermal energy
the kinetic energy of a substance atoms
thermal conduction
the transfer of energy as heat through a material
thermal conductor
a material through which energy can be transferred as heat
thermal insulator
a material that reduces or prevents the transfer of heat
convection
the transfer of thermal energy by the circulation or movement of a liquid or gas.
radiation
transfer of energy as electromagnetic waves
specific heat
the quantity of heat required to raise a unit mass of homogeneous material 1 K or 1 degrees celcius in a specified way given constant pressure and volume
states of matter
the physical forms of matter, which include solid,liquid,and gas
change of state
the change of a substance from one physical state to another
insulation
a substance that reduces the transfer of electricity,heat,or sound
heat engine
a machine that transforms heat into mechanical energy,or work
