Science Competency

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 mater 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 the following 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
