What's the quickest way to cool boiled eggs?
« on: 23/03/2016 22:50:01 »
Charl de Villiers asked the Naked Scientists:
   How would freshly-boiled eggs cool down the fastest?

By leaving them in a pan of cool water, in a breezy spot, or putting them out to cool down in the same breeze, but sans the water?

Thank you!
What do you think?

I would guess submerged in cold water, for the same reason that if you fall into an icy lake, you lose heat faster than standing in air at the same temperature -water's high heat capacity.

I agree with cheryl. The cold water will chill the eggs faster than the breeze. Not just because of the higher heat capacity, but also because it conducts heat much more quickly...

If you wanted to go to extremes, you could stand back and drop it in liquid nitrogen.
This would immediately raise the question of what is the fastest way to warm up a frozen egg....

In any case, it comes down to the thermal conductivity of eggs. If you chop the egg into smaller pieces, the heat can get out (or in) more quickly.
