Thermal Energy

The total energy (kinetic & potential)  of all the particles in a substance is called: 

• temperature
• thermal energy
• degrees
• mass

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

• temperature
• motion
• heat
• momentum

Heated air moves from baseboard heaters to the rest of a room in a process called: 

• conduction
• convection
• radiation
• insulation

A lizard basking (receiving heat from the light) in the sun is an example of: 

• Radiation
• Conduction
• Convection

A metal spoon warming in a bowl of soup is an example of: 

• Radiation

• Convection

Burning your feet on hot sand or concrete is an example of: 

• Radiation

• Convection

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.
