3.  Conductors make it easy for energy to flow through it and insulators cause the energy to go slower through it.  Also conductors are cold at the touch while insulators keep things warm such as wool socks.
4.  I would say that it would be better to use the copper pipe as an conductor because it is cold at the touch and it allows things to to flow easily.
5.  I would first get in my tent (conduction)  because trapped air makes warm air but the fire (radiation)  helps a lot too becuase it gives off hot air which does help.  So I would most likely first get inside my tent till I felt pretty warm and then stuff a lot of leaves and other things into my jacket because that helps keep you warm.  Then I would build my fire.  The fire would help the most though.
