Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
Two objects must be touching and it has to transfer heat
A hot object must be directly touching a cold object.
in thermal contact with each other
No, not if there's enough charge. Clouds in the sky transfer charge to the ground quite readily, without touching. When that happens, we call it "lightning".
The electron configuration of rubber (natural of artificial is such that there is a big gap between valance band and conduction band of electrons. Electrons has to make a transition from valence band to conduction band in order to conduct electricity.

2 objects must be touching each other in order to transfer heat.
It would be called a physical change, and would not be a chemical change at all. In order for a chemical change to occur, the original substances (reactants) must have different physical and chemical properties than the new substances (products).
the correct order is: pharynx, larynx, trachea, bronchus, bronchioles, alveoli
substances made by non-commutative reactions, where the ractants have to be put in a certain order.
in thermal contact with each other
