Consider 1 mole of supercooled water at -10°C. Calculate the entropy change of the water when the
supercooled water freezes at -10°C and 1 atm.
Useful data:
Cp (ice) = 38 J mol-1 K-1
Cp (water) 75J mol −1
K
-1
Afus H (0°C) 6026 J mol −1
Assume Cp (ice) and Cp (water) to be independent of temperature.
The molar enthalpy of vaporization of benzene at its normal boiling point (80.09°C) is 30.72 kJ/mol.
Assuming that AvapH and AvapS stay constant at their values at 80.09°C, calculate the value of
AvapG at 75.0°C, 80.09°C, and 85.0°C.
Hint: Remember that the liquid and vapor phases will be in equilibrium at the normal boiling point.
3. The entropy of an ideal gas is S = Nkg In V. Entropy is a state function rather than a path
function, and in this problem, you will show an example of the entropy change for an ideal gas
being the same when you go between the same two states by two different pathways.
A. Express ASV = S2 (V2) - S₁(V1), the change in entropy upon changing the volume from V₁to
V2, at fixed particle number N and energy, U.
B. Express ASN = S₂(N₂) - S₁ (N₁), the change in entropy upon changing the particle number
from N₁ to N2, at fixed volume V and energy U.
C. Write an expression for the entropy change, AS, for a two-step process (V₁, N₁) →
(V2, N₁) → (V2, N₂) in which the volume changes first at fixed particle number, then the particle
number changes at fixed volume. Again, assume energy is constant.

- as a hiker in glacier national park, you need to keep the bears from getting at your food supply. 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?
