Specific heat of Al

  1. Feb 21, 2012 #1
    Does the value of specific heat change with phase?
    If yes, why so and what are its values for Al in liquid and solid phase.

    See this - http://hyperphysics.phy-astr.gsu.edu/hbase/tables/sphtt.html - at 20°C (293K), the value is about 900 J/kg-K.
