On a winter morning Meena touches the iron gate and the wooden door
On a winter morning Meena touches the iron gate and the wooden door. The iron feels much colder. She says the iron is at a lower temperature than the wood. Is she right?
Who do you think is right? Pick one.
The answer: Both are the same
Why
Meena's feeling is honest — the iron truly feels colder, so 'it IS colder' seems obvious. But both have sat in the same room all night, so both are at the same temperature. What differs is how fast each pulls heat FROM her hand. Iron is a good conductor: it drains warmth from her skin quickly, so her hand cools fast and reports 'cold'. Wood is a poor conductor: it takes heat slowly, so her hand barely cools. 'Cold' is really her skin measuring how fast heat leaves it, not the object's temperature. Test: on a hot afternoon a metal spoon in the sun feels HOTTER than a wooden one beside it, though both are equally hot — the metal just moves heat to you faster. Both are the same temperature; iron only feels colder because it steals your hand's heat quicker.
