Chapter 6 Flashcards
a measure of how hot or cold something is; specifically a measure of the average kinetic energy of the particles in an object
temperature
an increase in the size of a substance in response to an increase in the temperature of the substances
thermal expansion
the temperature at which molecular energy is at a minimum ( 0 k on kelvin scale or -237.16 c on the Celsius
absolute zero
the energy transferred between 2 objects that are at different temperatures
heat
the kinetic energy of a substances atoms
thermal energy
the transfer of energy as 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 movement of a liquid or a 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 degree c in a specified way given constant 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
