Energy & Heat

The movement of thermal energy from a warmer object to a cooler object is called 

• heat
• temperature
• motion
• momentum

No more energy can be removed from matter at

• its freezing point. 
• 0ºC.
• absolute zero.
• 273 K.

The law of conservation of energy states that when one form of energy is transformed into another,

• energy is destroyed in the process.
• no energy is destroyed in the process. 
• energy is created in the process.
• some amount of energy cannot be accounted for.

The total energy of all the particles in a substance is called 

• temperature.
• thermal energy.
• degrees.
• mass.

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

• thermal energy. 
• conduction.
• convection. 
• temperature. 

The transfer of energy by electromagnetic waves is called

• conduction. 
• convection.
• radiation.
• conservation. 

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 solid, such as bismuth, has 

• a definite shape, but not a definite volume. 
• a definite shape and a definite volume.
• a definite volume, but not a definite shape.
• neither a definite shape nor a definite volume.

In a system, when energy is transformed from one form to another,

• some energy is always destroyed.
• new energy is created.
• the total energy is conserved.
• all energy changes to friction. 

Heat is transferred from one particle of matter to another within an object or between two objects in a process called

• conduction.
• convection.
• radiation.
• insulation.
