The photo on the left shows a problem that was part of our problem set during our Thermodynamics class. In this problem, we were tasked to look for the volume change in vaporization for ammonia. The solution I used involved looking for the parameters that were needed to plug into the Rackett Equation, such as the critical temperature, volume, and compressibility factor. The Rackett equation allows the prediction of the behavior of gases under different temperatures and pressures, which is crucial in different industries, such as the petroleum refining industry.
