  1. Cesium Hydroxide has the highest pH possible, 15, and can dissolve glass.

    Glass is not actually solid but is a Thixotropic Liquid.

     

     

    thats like saying you could have a Ph of -1

     

    I'm 11 and I knew that!

  2. If you're talking about ordering online, I'm not sure whether it's reliable or not as I have never tried. But as far as purchases directly from the store, I've been very satisfied. Good products at bargain-basement prices. I bought 50 or so test tubes (pretty good sized, hold about 20 mL) for 4 bucks. Virtually all my chemistry supplies have come from the store.

    how did you manage that? thats not the online prices

    btw were is the store

  3. However, wearing that cloth in hopes of making yourself the invisible man will just get you arrested for public nudity.

  4. No it does not mean exactly that. Liquid in deodorant bottle is at great pressure. If it gets out it starts to evaporate. Any part that evaporates takes a lot of heat with it' date=' so liquid that remains ( for example on your body ) goes colder and colder as long as it is not yet completely evaporated. Fridges use this to make cold but there all the process goes in the copper tubes.

     

    In the same reason acetone or gasoline go rather cold if vessel is left open and even water that stands in open beaker at your desk is always some degrees colder than air around it. In respect of this "colder" liquids are those that evaporate fastest but only if they can freely evaporate.[/quote']

     

     

    (in stupid voice)cold is only the absence of heat:D

  5. Ah' date=' I see - thanks for the explination (Makes more sence now :D)

     

    Cheers,

    what the heck i thought i had brains until now, but hay im 11. I dont even take pre algebra

  6. You mean that you want to know a cold liquid, that remains cold? If that is what you mean, then I have to disappoint you. Such a liquid does not exist. Any cold object, exposed to room temperature, will finally reach that temperature. With good isolation you can make that process slow, but you cannot stop that. E.g. liquid nitrogen either becomes warmer (and then pressure builds up), or it evaporates and when all has evaporated, no liquid is left anymore.

    ya its called, get ready for a fancy word now, equilibrium, i think:D
