Thermal Energy and Heat

No more energy can be removed from matter at

• its freezing point.

• 0ºC

• 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

• silver

• air

• paper

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

• thermal energy.

• conduction

• convection

• temperature
