A Liquid That Turns Solid When Heated

Roland Piquepaille writes "There are some sure things in life, such as death and taxes. When you are heating a solid, you expect it will melt and when you're boiling water, you're pretty certain that it will turn into vapor. But what about a liquid that becomes solid when it's heated? Of course, it has already been done, for example in the chemical process of polymerization. But now, PhysicsWeb writes that a team of French physicists has discovered a law-breaking liquid that defies the rules. When you heat it between 45 and 75C, it becomes solid. But the process is fully reversible, and this is a world's premiere. When you decrease the temperature, this solid melts and turns again into a liquid. I'm not sure of the implications of such a phenomenon, but it's fascinating. Read more for essential details."

    Ice only turns into a solid when heated in Soviet Russia

    This liquid has immediate application in the construction of skyscrapers. Consider building a 100-floor building. We pair each solid steel beam with a hollow steel beam. We fill each hollow beam with this unique liquid.

    Now consider the following scenario. A raging fire occurs on the 70th floor. Normally, such a fire would threaten the top 30 floors if the fire were sufficiently hot. The top 30 floors could collapse into the 70th floor since the heat of the fire has weakened the supporting beams of the 70th floor.

    With liquid-reinforced steel beams, they should retain their supporting strength. The top 30 floors would be safe.

    If we had constructed the World Towers in New York City in this fashion, then they would not have collapsed on 2001 September 11.

    first he is not astroturfing. he is not posting it under a different identity.

    he isnt flat out saying my blog has this, but why should he have to?

    and why should we stop feeding him page views? because his site has some good info?

    No, it all depends on who's in the white house. And right now I'm disgusted of being american. I wouldn't be surprised if they called us assholes, because that's who's in charge right now.
