You need to be more specific about the bowls.

Unless the bowls had particularly conductive (thermally) bases, the
largest bowl would have cooled fastest. However, the smallest bowl,
being baby bear's bowl, is likely to have been cooler to start with (so
as not to burn baby bear).

Is the thickness proportional to the diameter, or the same in all three?

I agree with the -smallest- bowl.

This assumes that heat loss is uniform over the entire body surface.
This won't be the case. Heat loss will be much, much higher from the
surface of the porridge than from the bowl. In fact, most of the heat
loss will be evaporative, at least during the first few minutes. As
such, the largest bowl will cool fastest, despite the smaller
surface:volume ratio.

But wouldn't the evaporative losses still be related to x squared, whilst
the available energy is x cubed? It's just an alternative form of surface
loss.

I think this is wrong. Daddy's porrisge has greatest surface area, so
loses most joules per minute, but it also has a temp drop of less deg C
per joule, since there is more porridge there. Quite simply it comes
down to the area/volume ratio. In both exposed porridge area and bowl
area, daddys porridge has least area per voume, baby's greatest.

If and only if all other things are equal, babys cools fastest. In the
real world of course, other things are more often not equal, eg baby's
was probably served at a lower temp to start with..

It depends. Were the bowl U values compliant with BRs? Was the porridge
old fashioned porridge, ready brek, rice porridge, or wheat porridge?
Were the portions subject to portion control? Was the porridge served
litigiously hot? Or had it passed a care range valve designed to limit
it to 43C?

NT

I suggest Daddy bear's was warmed on "full power" for longer. -
Although thinking about it microwave ovens were probably not around
back then.
- clearly the witness statement from Goldilocks, does not specify the
heating method, and therefore would not stand up in court.

Of course Mummy bear may have added some milk to Baby bear's bowl
before serving.

Interestingly, the version at :-
http://www.ongoing-tales.com/SERIALS...oldilocks.html
Talks about soup, not porridge.

Was the porridge supplied by Ye Olde "Ronald McDonald", and came with a
label - "Careful Porridge may be hot"..

In fact, reading the link above, it says that Daddy bear's soup was too
hot with Pepper. - aha, so it was "spicy" hot, rather than "heat" hot
after all.

In the real world of course

How many bears in the real world make porridge??

Surely that should be "Caution, porridge may be hot after heating"

Thanks for interesting replies (i'm sure there'll be more!) I like
some others was working on the basis that the largest suface area of
porridge would give the quickest cooling.

OK, you've two bowls of hot water in identical
situations. One is covered with large soapy
bubbles (bubble bath). Which will cool quicker?
The surface area of the bubbles is larger than
that of the surface area of the non-bubbly water.

The bubbles will act as insulation, making the soup stay hot for longer.
Think of a hot water cylinder, one covered in insulation. The insulated one
has a greater surface area, but I bet it stays hot longer!

The contents of the bowl with bubbles is not homgeneous, the thermal
resistance of the bubbles is different to that of the water so it
complicates the model rather. I expect the rate of evaporation from the
bowls will be rather different as well.

The largest surface area will lost heat more quickly, but there is a
greater mass and depth to consider.

Ah, I see you have been there before!!

I think OP meant porridge.
The answer is that AOTBE the smallest cools quickest. The smaller a
thing is the greater the ratio of surface area to volume. The amount of
heat is proportional to the volume but the rate of heat loss is
proportional to the surface area.

The OP put that in his text. If you think MF doesn't know what
was meant, or would not be able to interpret porrage, porridge,
porage, or even porige correctly, then you underestimate MF's
deliberate obtuseness, IMO. Hopefully MF will not linger this
time, but the apparent desire to troll may dismiss this hope.

I, too, noticed that.
I gave now corrected the errant header. Both spelling mistooks and ghastly
punctuation abound in wtitthen texts in the UK.
And what is "porage", then? Always spelt thus as in Scott's Porage Oats!
But, it does not have to be made from oats - could be concocted out of peas
or certain kinds of beans.
And "doing porridge" is slang for spending a correctional or penal time in
gaol.

Isn't it funny
How a bear likes honey
Buzz! Buzz! Buzz!
I wonder why he does?

It's a very funny thought
that, if Bears were Bees
They'd build their nests at the bottom of trees
And that being so (if Bees were Bears)
We shouldn't have to climb up all these stairs

3/4 power (800 watt oven) and exactly 3 minutes. I do this every

Dollop of preserved cranberries in the bottom before the oats, and don't

If they were China they'd be pandas. Whilst the species has been
identified fairly recently as a type of bear, pandas are solitary
animals.

Howevr they do eat predominantly cereal crops. Bamboo.

If the tale has a modicum of truth the bowls must have contained rice
in the original translation. Perhaps the father bear would have had
more curry powder on his?

I just tried it in the microwave - it took longer than in a saucepan on
the gas and was sorta lumpy.
Most bears reckon it's best with carnation milk and a pinch of demerara
sugar.

Surely it depends on the size of the combi, and the initial temperature
it comes out of the mains?
In winter, you may only get 5l/min of piping hot porridge.
