Does heat generate additional gravity

  1. Aug 28, 2010 #1
    Considering E=mc^2... (solved for m; m=E/c^2)

    If I heat up an object, does it generate more gravity as it gets hotter?

    What about adding other types of energy to the object? (pick your energy form - save potential I would think)

    (Basically, does adding energy to an object increase it's gravitational mass)

    If you heat the object by adding energy, and not just compressing the object or some means that doesn't require the addition of energy, then yes.

    If one form of energy is equivalent to mass, then all other forms of energy must be equivalent to mass as well. For an argument to this effect, see this link: http://www.lightandmatter.com/html_books/6mr/ch01/ch01.html#Section1.3 [Broken]
