1. Determine the compressibility factor for methane at 20.0 MPa and 0.00C.
2. In 1879, the French physicist Emile Amagat generated experimental data in a mine shaft at Verpilleux, France, for his research on the compressibility of gases. There he used a vertical column of mercury 327 m high to measure the compressibility of nitrogen at a pressure of 430. atm. Assuming the temperature at the bottom of the mine shaft was 30.0°C, use the compressibility charts to determine the value of the compressibility factor for nitrogen under these conditions.
