In the same cool room, Manav touches an iron chair leg and a wooden seat
In the same cool room, Manav touches an iron chair leg and a wooden seat. The iron feels colder. Manav says the iron is actually colder than the wood. His sister says both are at the same temperature. Who is right?
Who do you think is right? Pick one.
The answer: His sister is right, both are the same temperature; iron pulls heat from your hand faster
Why
Manav is trusting his hand as a thermometer, but a hand does not actually measure temperature — it senses how fast heat is leaving it or entering it. Both objects have been sitting in the same cool room, so both are at room temperature. When you touch the iron, it carries heat away from your skin very quickly (metal is a good conductor), so your hand loses warmth fast and reports 'cold'. Wood carries heat away slowly (it is an insulator), so your hand barely cools and it feels milder. Test it: leave a real thermometer on the iron leg and another on the wooden seat for a while — both settle on the same number, even though your hand insists the iron is colder. This is also why a hot pan gets a wooden or plastic handle, not a metal one. His sister is right: both are at the same temperature; the iron only feels colder because it draws heat from your hand faster than the wood does.
