Mercury: expansion with temperature

  1. Apr 15, 2009 #1
    I have found this fantastic calculator:

    http://www.ajdesigner.com/phptherma...pansion_equation_volumetric_volume_change.php

    I need to use it to work out how much Mercury I need to expand it by 50 Litres under temperature.

    First things first though, i’m getting completely improbable answers out of the calculator because i am entering the wrong 'volumetric expansion coefficent (b)'.

    here is what i am entering:

    volumetric expansion coefficent (b): .00182
    initial volume (Vinitial): 500 Litres
    final temperature (Tfinal):67 decC
    initial temperature (Tinitial):1 degC

    And my results:

    500 Litres ---> expands to ---> 560.06 Litres

    Is this correct? I was expecting a greater expansion.

    Thank you.

    That exapansion coefficent is about 2/1000 or 1/500
    So about 1l/deg C, and 66degC gives you about 60 extra litres litres
