Default Whose Porrige should have been coolest?

Have we been lied to all these years?

Assuming that mummy bear just made the one pot of porridge, that the
three bowls were the same shape and made of the same material and the
ambient temerature was the same throughout the room. Daddy bear's bowl
is larger tham mummy bear's and baby bear's is the smalleset, whose
porridge should cool the fastest?

You need to be more specific about the bowls.

All made from the same type of china, and the same shape (a bit like
the bottom third of our planet only hollow. one 4" dia one 5" one 6".

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

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.

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.

And which was dished out first.

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..

In the real world of course

How many bears in the real world make porridge??

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

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!

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.

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
skimp on the milk. No salt.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Andy Dingley
saying something like:

I only m/w porridge now, can't be arsed with the faffing about of
boiling things in pots.

Yumm.

No salt.

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.

I used to put the milk/water/oats in the microwave before I went to bed,
and set the timer so the porridge was waiting for me when I came down in
the morning.


I suppose that might make you get up. But I'd probably sleep through the
alarm as I almost always do.

Not having a mw (from choice) and still loving porage I let the oats sit
overnight in the liquid. They then cook more quickly in the morning.But I
don't mind the time taken to cook, it gives me time to come round.

They say that you need less sleep as you age.

They lie.

When (in a previous lifetime) I worked at Imperial College the stoods
there for a rag week stunt one year made a candle out of a tanker-load
(courtesy of BP) of hot wax poured into a mould made of some
Russian-gas-pipeline-type steel pipe. They allowed IIRC a week for it to
cool down before attempting to extract it but even then the inside was
still liquid.

Anyway (and to get back to the point (if there was one :-)) where
does it say that all 3 bears' bowls _were_ the same sizes?
