Question

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, while that for liquid water is 75.5 J/Mole-K, while delta H_fusion = 6.01 kJ/mole. One mole of liquid water, initially at -20 degree C is allowed to come to equilibrium at that temperature. 5.16 kJ of heat are released to the temperature bath during this process. Find delta S_univ for this process. A cube of ice (1.00 mole) initially at -20 C vacuum, is suddenly heated with a in a flash of light and allowed to come to equilibrium at which point the temperature is determined to be 10 C. Find delta S_univ for this process. A spring has internal energy E, which is a function of both the temperature (T) and the distance (s) that it is stretched from the equilibrium length of (S_0). For a particular spring it is known that: (partialdifferential E/partialdifferential s)_T = c(s - s_0) (partialdifferential E/partialdifferential T)_s = e
