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.

Mittens help keep your hands warm in winter because:

• They are conductors of heat.
• They are fuzzy.
• They are conductors of electrical energy.
• They are insulators.

A worker for an electrical company is preparing to fix a power line. Why would he put on rubber gloves before working with any power lines?

• Rubber is a poor conductor of heat but a good conductor of electricity
• Rubber is a good conductor of heat but a poor conductor of electricity
• Rubber is a poor conductor of heat and electricity
• Rubber is a good conductor of heat and electricity
