Thermal Energy and Heat - Chapter Test A

No more energy can be removed from matter at

• its freezing point.

• 0°C.

• absolute zero.

• 273 K.

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.

A material that conducts heat poorly is called a(n)

• insulator.

• conductor.

• metal.

• radiator.

The amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin is called its

• specific heat.

• heat transfer.

• change of state.

• melting point.

As the thermal energy of matter increases, its particles usually spread out, causing

• condensation.

• evaporation.

• thermal expansion.

• vaporization.

Heated air moves from baseboard heaters to the rest of a room in a process called:

• conduction

• convection

• radiation

• insulation

Which of these is a good conductor?

• wood

• paper

• silver

• air

A measure of the average kinetic energy of the individual particles in an object is called:

• thermal energy

• conduction

• convection

• temperature
