3i have a qn which i need an answer
In winter season we feel dat an iron bar is very cool to touch compared to a fire wood why it happens but we know that the temperature shud be the same.
this qn was given in resnick.
1a refrigerator extracts heat from freezing chamber.some work is done on it by an electric motor and rejects heat into the surrounding air thus worming the air.therefore the room cannot be cooled but heated slightly.
