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

• thermal energy
• conduction
• convection
• temperature
