Question

1. Atmospheric Pressure: 0.996792499 atm → converted to psi → 14.64881 psi
2. Use 12.0 cm for the internal diameter of the spherical vessel if you need it.
3. Use 100 psig for T = 20 °C. (psig is the gauge pressure in psi, in contrast to the psia being the absolute pressure in psi.) Don't forget to convert the gauge pressure to the absolute pressure using the atmospheric-pressure data from the weather site.
4. Calculate (1) the absolute pressure in psia and (2) the gauge pressure in psig for T = 100 °C, 0 °C, and liquid-nitrogen boiling temperature for an ideal gas.

Please do number 4, all information is provided.
