Thermodynamics and Kinetics: Part 2

Today’s lecture is 51 minutes long. Looks like it was winter when this was filmed. The students are wearing jackets.

The ideal gas thermometer gives us the concept of absolute zero. Based on Boyle’s law: limit as p approaches zero of pV = constant.

p1V1 = p2V2

Boiling pt of water is 100 C and freezing pt of H2O is 0C. We have to connect those two dots. We use a linear interpolation. The x axis is intercepted. There pV=0. Negative pressure and volume “don’t make sense.” -273.15 C. K = C + 273.15

The triple point of H2O is 273.16 K and the pressure where water is in EQ for s, g and l. 6.1 x 10^-3 bar.

Slope = Rise/Run = f(triple point)/273.16 = R
RT = pV/n for an ideal gas
PV = nRT
V = f (n, P, T) is an equation of state

Compressibility factor = Z = PV/RT
Z = V real/V ideal

Virial factor; Taylor expand the fudge factor
PV/RT = Z = 1 + x/Vreal + y/V2real…

Van der Waals equation of state
(P + a/v2)(V-b) = RT
b is the volume per mole of hard spheres
a describes intermolebular attraction
V bar is the probability of interaction

Work = Force x Distace = Fd
Expansion or compression work.
F = P external x Area
W = P ext x area x length
Work on the system is +, work done by the system is –

dw = -p ext dV, p ext is path dependent
functions of state are path independent

Ar (g1, p2, V1) = Ar (g1, p2, V2)
p1 T2
T2 > T1 is positive q
T2 < T1 is negative q

adiabatic means no heat
q depends upon path
