Question 5(1 point)
Water has a critical temperature and pressure of 647K and 22MPa, respectively.
In a laboratory, water is held at 970K and 11MPa. (the same conditions as the previous question)
An engineer needs an equation of state to calculate the approximate molar volume of water at these conditions. The engineer wants the calculated molar volume of the water to be within 10% error of the actual molar volume.
True or false: Under these conditions, the ideal gas equation of state will give an estimate of molar volume for water that is within 10% of the actual molar volume.
