Please answer the question number 8.
For a virial gas (to second order) this is not so obvious since: (partialdifferential E/partialdifferential V)_T = RT^2/V^2 dB/dT where B = B(T) is the second virial coefficient. Show that in order to be consistent with the second law of thermodynamics B(T) = g/T, where e, and g are constants. As you might know, the melting point of ice is 0 degree C. The heat capacity at constant pressure of ice is 37.8 J/mole-K,...

ideal gas law questions
Movable piston A cylinder contains an ideal gas that is at room temperature. The cylinder is sealed with a piston of mass M and cross-sectional area A that is free to move up or down without friction. No gas can enter or leave the cylinder. The piston is at rest. Atmospheric pressure (i.e. the pressure of the air surrounding the cylinder) is P. a. In the space provided, draw a free-body diagram for the piston. Ideal...
