Concerning the recent crash one of the TV commentators said that it was better for the airplanes survivability that the water in the Hudson is cold and not warm. the reason he said is that cold water is *harder* than warm water and made for better ditching conditions. Any truth to this. No - cold water is less dense than warm water. That's why ice floats. |

You answered my post and my post hasn't even appeared on my news service (Giga News)yet. I made the post 65 minutes ago. Can you tell me what time stamp in on my original post. Thanks |

Thanks Tom is an extraterrestrial. The space-time continuum does not apply to him. But it does apply to ducks. |

Thanks I think it's Giganews. Same thing here. I posted a response shortly after Tom and it never showed up, yet he answered it. Eisboch |

Thanks Giganews is screwing up. I'm seeing the same odd behavior. Still haven't seen you original post. I heard that guy too, and thought he was full of it. Cold water is more dense than warmer water, which is why it sinks. You've heard of thermoclines. I've even felt it wading in the ocean. I don't think it makes a difference in landing a plane on it though. Ice is an expanded state of water. Takes of more space than liquid water. That's why it floats. But ice is harder than water. At least I think it is when I fall and my ass lands on it. Doesn't hurt when I fall the same distance into the water. Diamonds are real hard, and are forever. BTW, I'm not a scientist. --Vic |

Methinks you are wrong. Ice floats on water. The process of freezing is a strange one. First it contracts, then it expands and breaks water pipes. I suppose this is sort of boating related.... sigh. Sucked you in did we? :) As water gets colder it gets denser. However as it approaches freezing the way the water molecules start crystalizing results in a less dense solid. There are very few things that behave this way and water is one of them. It is a good thing to otherwise the bottom of the ocean and big lakes would be frozen forever. Yep - the only thing I remember from my cold water survival course with Dr. Murray Hamlet (which was a blast by the way - cold, but a lot of fun) was that freezing water is less dense than warmer waters. Forgot all about the whole hydrogen bond thing. However, they are pulling the Yamahas off the Canyon 33 tomorrow, so maybe we can move it next week. So that makes it an official boating post. :) |

Water expands as it becomes colder. You can't have expansion in a liquid without it becoming less dense. It's why ice floats. Wait - let me check on something. Erm....sorry - I'm right, but I'm wrong at the same time. I forgot one little minor detail. Water expands at the freezing point - otherwise, it acts just like other liquids. Water does become denser as it approaches the freezing point. Water temp in the Hudson was 41 degrees F which is almost at the point of freezing. http://en.wikipedia.org/wiki/Water_(..._water_and_ice So the newsguy was right, although I doubt that made much of a difference. But so what if you get hypothermia? Bottom line, get out alive. |
