Why does hot soup get cold?
Hot soup gets cold because its warmth slowly floats away into the air.
Pip’s answer
- Hot soup gets cold because its warmth slowly floats away into the air.
- In hot soup, tiny bits jiggle super fast, like wiggly dancers!
- They bump the cooler air and bowl, sharing their energy, so they slow down.
- Ooh, warmth always moves from hot things to cooler things, everywhere!
For grown-ups
Heat always flows from warmer things to cooler things. Hot soup loses heat to the cooler air, bowl and spoon, and through evaporation (the steam you see). Blowing on soup speeds this up by moving warm, moist air away from the surface.
Ask your child: Why does blowing on hot food help it cool?
