Consider the adiabatic expansion of an ideal gas into a vacuum where the external pressure equals zero. What is ?rev and ∆? for such an experiment? What is ∆? for the ideal gas?
Homework Answers
For adiabatic process,
dQ = 0
we know , dQ = dE + dW
Since dQ = 0
0 = dE - pdV
dE = -pdV
Wrev = - pdV
∆? = n Cv dT ( ∆? is internal energy )

Item 10 In this problem you are to consider an adiabatic expansion of an ideal diatomic gas, which means that the gas expands with no addition or subtraction of heat. Part A Assume that the gas is initially at pressure Po, volume V. and temperature To. In addition, assume that the temperature of the gas is such that you can neglect vibrational degrees of freedom. Thus, the ratio of heat capacities is y=Cp/Cy = 7/5. Find an analytic expression for...
