Variation of liquid density with temperature

  1. Jan 28, 2009 #1
    I am looking for information on the density of a liquid at lower temperatures. I have it at 15C as 725 kg/m^3. The fluid is avgas 100LL.

    I wish to determine it at lower temperatures. I believe that the change in liquid densitiess is rather small for temperature changes, but I can't verify this.

    Any help is appreciated.

    There isn't a general physical law - it depends on the chemistry of the substance.
    If avgas is a standard commercial substance (sort of aviation fuel?) then there wil be detailed tables for it.
    Have you tried google?

    Yes I have without any luck, in addition to wikipedia and other sources. I just found this forum and thought that I would give it a try.
