(16 cards)
Temperature
A measure of how hot or cold something is, specially a measure of the average kinetic energy of the particles in an object
Thermal expansion
an increase in the in the size of a substance in response to an increase in the temperature of the substance
Absolute zero
the temperature at which molecular
Heat
the energy transferred between objects that are at different temperatures
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
Convection
the transfer of thermal energy by the circulation of movement of a liquid or gas
Radiation
the transfer of energy as electromagnetic waves
Specific heat
the quantity of heat required to raise a unit mass of homogeneous material 1 K or 1C in a specific 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
Thermal pollution
a temperature increased in a body of water that is caused by human activity and that has a harmful effect on water quality and on the ability of that body of water to support life
