Chapter 6 Flashcards
a measure of how hot(or cold) something is; specifically, a measure of the average kinetic energy of the particals in an object
tempature
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 a minimum (0k on the kelvin scale or -273.16c on the Celsius scale)
Absolute zero
the energy transferred between two objects that are at different tempatures
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 thransferred as heat
thermal monductor
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
radiation
the quantity of heat required to raise a unit mass of homogeneous material 1k or 1c 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
