2. Air trapped among the layers of newspaper is a poor conductor of heat. So. this helps him to keep himself warm.
3. Stainless steel plans are usually provided with copper bottoms. The answer will be copper is a better conductor of heat than the stainless steel is a alloy and copper is a metal. That is why the copper is a good conductor of heat.

Answer:
1) The chocolate absorbs the thermal energy away from your hand. (Absorption of thermal energy by conduction)
2) The newspaper act a s a barrier between the direct cold from the surrounding around him. Here, air trapped in the newspaper acts as a source of heat for him too as it is a bad conductor of heat, (Heat in terms of taking heat away from the man, no the surroundings)
3) Copper is a better conductor of heat and so for maximum efficiency copper is used.
