CH 353 Physical Chemistry I (54655) Spring 2008 Name:____________________ Bersuker Exam 1, Feb 15 th , 2008 EID:____________________ I. (15 points) Answer True or False and explain why . (a) U remains constant in every isothermal process in a closed system. (b) for every adiabatic process in a closed system. 0 = Δ T (c) At constant pressure, change in enthalpy equals change in internal energy. (d) For all ideal gases 4 . 1 / , , = = m V m p C C γ . (e) The virial constants A, B, and C in the corrections to the equation of state of perfect gases are different for different gases. (a) False – Only for perfect gases. (b) False – Only hold for isolated case. (c) False – Must account for the pdV work to know. In the case of ideal gases, they are within a constant of each other: . V p C C U H = Δ Δ (d) False – Only for diatomic ideal gases. (e) True – The virial coefficients are both molecule and temperature dependent, though one may write one of the three in terms of the other two; in which case, only two of the three
