Chapter 2, Problem 80AP

(a) Use the ideal gas equation to estimate the temperature at which 1.00 kg of steam (molar mass $M=18.0$ g/mol) at a pressure of $1.50\times {10}^6$ Pa occupies a volume of 0.220 m³. (b) The van der Waals constants for water are $a=0.5537$ Pa m⁶/mol² and $b=3.049\times {10}^{-5}$ m³/mol. Use the Van der Waals equation of state to estimate the temperature under the same conditions. (c) The actual temperature is 779 K. Which estimate is better? `
