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.
