Ramesh's mother says wet clothes dry faster on a windy day
Ramesh's mother says wet clothes dry faster on a windy day. Ramesh says wind doesn't add any heat, so it shouldn't make a difference. Who is right?
Who do you think is right? Pick one.
The answer: Mother is right
Why
Credit Ramesh's real insight: wind carries no heat, and drying does need energy — he's right about that half. What he misses is HOW clothes dry. Water leaves as invisible vapour; right above wet cloth sits a thin layer of air already packed with that vapour, which slows more from leaving. Wind sweeps that damp layer away and brings dry air, so water escapes faster — no extra heat needed. Picture blowing on hot tea: your breath adds no heat, yet it cools faster because you clear the vapour above it. Mother is right — wind speeds drying by removing moist air, not by warming.
