    Why can't astronaut soup be heated to more than 95 degrees Celsius? What will happen if it does?

    It's not a good idea to heat things up in an oxygen-rich atmosphere:


    From ntrs.nasa.gov:

    FLAMMABLE AND TOXIC MATERIALS
    IN THE OXYGEN ATMOSPHERE
    OF MANNED SPACECRAFT

    ABSTRACT
    A preliminary study of the considerations nec-
    essary in selecting materials for use in an oxygen-
    rich atmosphere revealed that a major design effort
    must be directed toward reducing the toxic and flam-
    mable contaminants of the atmosphere. The effect
    of zero gravity in preventing convection is one as-
    pect of research that deserves considerable effort
    since heat transfer and flammability are two major
    fields directly affected. Other research is needed
    in human tolerances, static electricity, removal of
    low -molecular -weight gas, fire extinguishment,
    overall characteristics of materials exposed for long
    periods in pure oxygen, and in the development of
    adequate test procedures.

    It also might have something to do with them living in less than 1 atmosphere of pressure...which would lower the boiling point of water.
