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? |

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. |

Daddy bear's bowl is larger than mummy bear's and baby bear's is the smallest, whose porridge should cool the fastest? Unless you intend some trick, then the baby's will. I agree with the -smallest- bowl. |

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. -- Grunff |

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. Christian. |

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.. NT |

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! Christian. |

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. cheers Jacob |

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. |

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. |

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember saying something like: Have we been lied to all these years?

If they'd been cooked in the microwave they'd all be blisteringly hot and remove the lining from the mouth, so it's a daft question. -- Dave |

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. cheers Biffo |

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. Mary |

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. No problem, just install dual Combis! |

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? |
