Hint: Remember the Energy Change Formula
The movement of thermal energy from a warmer object to a cooler object is called
heat
temperature
motion
momentum
The transfer of energy by electromagnetic waves is called
conduction
convection
radiation
insulation
Heat transfer occurs
In many directions
both from warm objects to colder ones and from cold objects to warmer ones.
only from warm objects to colder ones.
only from cold objects to warmer ones.
Heated air moves from baseboard heaters to the rest of a room in a process called
conduction
convection
radiation
insulation
A measure of the average kinetic energy of the individual particles in an object is called
thermal energy
conduction
convection
temperature

True
False
During conduction heat is transferred by the movement of currents within a fluid.
True
False
Trapped air is a good conductor because it reduces heat transfer.
True
False
As most substances are cooled, they expand.
