Energy, Heat, and Temperature

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

• thermal energy
• conduction
• convection
• temperature

When you touch something that feels cold, 

• heat from your hand moves into the cold substance.
• coldness moves from the cold substance into your hand.
• it melts.
• it freezes.

If two objects have different temperatures, heat will flow from the warmer object to the cooler one UNTIL ____________

• one reaches a temperature of zero

• they both have an equal temperature

• one runs out of energy
