6. We used the constant volume heat capacity, Cv, when we talked about
thermodynamic cycles. It acts as a proportionality constant between energy and
temperature: dU = C₁dT.
You can also define a heat capacity for constant pressure processes, Cp. You can think
of enthalpy playing a similar role to energy, but for constant pressure processes

Starting from the definition of enthalpy, H = U + PV, find the relationship between Cy
and Cp for an ideal gas.
Pure membranes of dipalmitoyl lecithin phospholipids are models of biological membranes. They melt
= 41°C. Reversible melting experiments indicate that
at Tm
AHm=37.7 kJ mol-1. Calculate:
A. The entropy of melting, ASm-
B. The Gibbs free energy of melting, AGm-
C. Does the membrane become more or less ordered upon melting?
D. There are 32 rotatable CH2
CH2 bonds in each molecule that can rotate more freely if the
membrane melts. What is the increase in multiplicity on melting a mole of bonds?
5. Heat capacity often has a temperature dependence for real molecules, particularly if
you go over a large temperature range. The heat capacity for liquid n-butane can be
fit to the equation
Cp(T) = a + bT
where a = 100 J K₁₁ mol¹ and b = 0.1067 J K² mol¹ from its freezing point (T = 140 K)
to its boiling point (T₁ = 270 K).
A. Compute AH for heating butane from 170 K to 270 K.
B. Compute AS for the same temperature range.

You find a campground that is near an outcropping of ice. Part of the outcropping forms a feta=51.5* slopeup that leads to a verticle cliff. You decide that this is an idea place to hang your food supply out of bear reach. You put all of your food into a burlap sack, tie a rope to the sack, and then tie a bag full of rocks to the other end of the rope to act as an anchor. You currently have 18.5 kg of food left for the rest of your trip, so you put 18.5 kg of rocks in the anchor bag to balance it out. what happens when you lower the food bag over the edge and let go of the anchor bag?
