1 kg of nitrogen is contained in a piston-cylinder device. The nitrogen is isothermally compressed from P = 1 bar to P = 10 bar at T = 300 K. Find the initial volume, final volume, and work and heat added to or removed from the nitrogen.

A. Assume nitrogen behaves as an ideal gas. B. Use Figure 2-3 as much as possible. If you need an equation of state, use the van der Waals equa- tion, with a = 1.37 x 10 bar cm/mol² and b = 38.6 cm³/mol. Problems 3-27 through 3-29 involve the same com- pound that was considered in Chapter 2, Problems 2-22 through 2-26: A molecular weight of 50 lb/lb-mol A normal melting point of 50°F A normal boiling point of 150°F A constant heat capacity in the solid phase of C₂ 0.7 BTU/lb °R A constant heat capacity in the liquid phase of C₂=0.85 BTU/lb.°R A constant density in the solid phase of p = 40 lb/ft³ A constant density in the liquid phase of p = 30 lb/ft³ An ideal gas heat capacity of C; = 1 - 7/1200 + T2x 10-6BTU/lb.
