Reversible isothermal process

  1. Mar 29, 2008 #1
    I was just wondering if in a reversible isothermal process, there is a change in internal energy.
    I know that for the isothermal forward process the temperature is constant so internal energy is constant? What really stumps me is the word reversible.

    In general, yes, the internal energy can change in a reversible isothermal process. (An exception exists for the case of an ideal gas, whose internal energy is a function of temperature only.)
