Describe how building codes relate to flooring.
What will be an ideal response?
Building codes specify flammability requirements for carpets in various locations and occupancies. The flame resistance of carpets is most commonly ascertained by the Flooring Radiant Panel Test. A carpet specimen is mounted on the floor of a test chamber and exposed to intense radiant heat from above, and the rate of flame spread is measured.

This problem concerns a compound for which the following data is available:
Critical Temperature = 1200 K Critical Pressure = 30 bar Enthalpy of Vaporization at atmospheric pressure = 5000 J/mol. Boiling point at one bar of pressure = 500 K Acentric factor = 0.6 Equation of state for gas/vaporphase: Z = 1 + bP2/T where b = 1 K/bar2 Approximate molar volume of liquid = 200 cm3/mol A) Use the Claussius-Clapeyron Equation to estimate the vapor pressure at T=550 K. B) Use the shortcut equation to estimate the vapor pressure at T=550 K. C) Indicate which of the two estimates generated in questions A and B is more reliable, and EXPLAIN WHY. D) Find a general expression for the fugacity for this compound in the vapor/gas phase, as a function of temperature and pressure. For full credit, the equation should be an algebraic equation (not a differential equation) and should contain only P, T, f and constants. E) Give your best estimates of the liquid phase fugacity and the vapor phase fugacity for this compound, each at T=550 K and P=20 bar.
