Heat and heat technology Flashcards
Temperature
The measure of the average KE of the particles in an object.
Thermal expansion
An increase in the size of a substance in response to an increase in temp of the substance
Absolute zero
The temp at which molecular energy is at a minimum 0K
Heat
The energy transferred between objects that are at different temp
Thermal energy
the KE of a substance atom
Thermal conductor
A material through which energy can be transferred as heat
Thermal insolator
A material that reduces the transfer of heat
Convection
The transfer of TE by the circulation or movement of a liquid or a gas.
Specific heat
The amount of energy needed to change the temp of l kg of a substance by 1 degree C
State of matter
The physical forms of matter
Change of state
The change of a substance from one physical state to another
Insulation
A substance that reduces the transfer of electricity heat and sound
Heat engine
A machine that transforms heat into mechanical energy
Thermal pollution
The excessive heating of a body of water
Radiation
The transfer of energy as electromagnetic waves
