Heat diffusion throughout a sphere

  1. Jan 18, 2006 #1
    Hey there I was wondering if someone maybe be able to help me with a couple of questions I have.

    I attach a set of equations the help define the heat diffusion throughout a sphere could you please tell me;

    in V=rT What is V when r is the radius of the sphere and T is the temperature ?

    and also What is the symbol V with the bar above it??

    and in the last equation on the attachement, is s the entropy??

    If you can help me I would be very greatful

    Thanks for any help possible
