Chapter 6.1-6.4 Flashcards
temperature
a measure of the average kinetic energy of the particles in an object
thermal expansion
the increase in volume of a substance because of an increase in temperature
absolute zero
the lowest temperature on the Kelvin scale
heat
the energy transferred between objects that are at different tempurtures
thermal energy
the 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 as heat
thermal insulator
a material that reduces or prevents the transfer of heat
covection
the transfer of thermal energy by the circulation or movement of liquid or gas
radiation
the transfer of energy as electromagnetic waves
specific heat
the amount of energy needed to change the temperature of 1kg of a substance by 1c
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 into mechanical energy, or work
