Answer:
Cold and Hot are relative terms and are largely based on perception. If you put your hand against something that immediately begins withdrawing heat from the skin, your nerve endings will register ‘cold’ and start sending the appropriate signals to the brain to say the object is cold. If you touch an object that is a very good insulator, such that it reflects the heat from your body back at you, then your skin will begin to warm up since your body is much warmer than the air it’s come accustomed to touching. Your brain will feel that object as ‘warm’, even if it is the same temperature as the ‘cold’ object but just a very good insulator.
If the ‘hot’ object is a very good heat conductor then it will only register as hot if it is actually hotter than your hand when you touch it. Thus heat will flow into the hand, warming it up and triggering the nerves to signal ‘hot’.
