Pressure of a solid body

  1. Jul 2, 2013 #1
    Hi. Consider a solid body placed in vacuum. How much is its pressure? Can we describe this body using thermodynamics if its pressure is zero?

    There can be a pressure in the interior, and it depends on the internal structure of the material.
    For thermodynamics in solid materials, pressure is usually not very important (unless you consider the core of earth or similar extreme materials).
