Question
A sample of 70 mmol Kr (g) expands reversibly and isothermally at 100 °C
from 5.25 cm3 to 6.29 cm³, and the internal energy of the sample is known to increase by
83.5 J. Use the virial equation of state up to the second coefficient B =-28.7 cm3 mol- to
calculate w, q, and AH for this change of state. The virial equation truncated to the second
coefficient is given by:
RT
