    Calculating Heat Transfer in a Reversible Isothermal Process with a Slow Leak

    Homework Statement Rigid tank volume .5m^3 initially evacuated. Tiny hole develops, air seeps in @ 1 bar and 21 degrees C. Pressure in tank reaches 1 bar, slow leak so temp remains 21 deg C inside tank. What's amount of heat transfer? Homework Equations Q=T[S(2)-S(1)] Pv=nRT The...
