Heat, Temperature, Thermal Energy

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

• heat

• temperature

• motion

• momentum

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

• thermal energy

• conduction

• convection

• temperature

The temperature of a substance increases as___.

• the substance expands
• the average kinetic energy of its particles increases
• the substance's volume increases
• the substance's mass increases

You're holding hands with your best friend.  Your friend's hands are REALLY warm and yours are really cold.  After a few minutes, this has changed.  How might you explain what happened?

• The cold energy from your hand transferred to your friend's hand through conduction.
• The heat energy from your friend's hand transferred to your hand through conduction. 
• The cold energy from your hand transferred to your friend's hand through convection.
• The heat energy from your friend's hand transferred to your hand through convection.
