Question

Using an understanding of thermodynamics, explain what is inaccurate about the following statement overheard at the Grand Canyon on a cool November morning: "This rock is making me cold."

Answer 1

The second law of thermodynamics says that heat flows naturally from an object at a higher temperature to an object at a lower temperature, and heat doesn’t flow in the opposite direction of its own accord.

The law is certainly borne out in everyday observation — have we ever noticed an object getting colder than its surroundings unless another object was doing some kind of work? Or we can force heat to flow away from an object when it would naturally flow into it if you do some work — as with refrigerators or air conditioners — but heat doesn’t go in that direction by itself.

Thus , when in the month of november our body is liitle bit in more temperature then the surrounding and the heat is transferred from the body to the rock. So we feel the cold from the rock.
