Chapter 11 - Condensed phases

Example 1 - pg 271

In [1]:
#calculate the Vapor Pressure
#Initialization of variables
A=7.6546
B=1686.8
T=60+273.2
#calculations
logP=A-B/T
P=10**logP
#results
print '%s %.1f %s' %("Vapor Pressure =",P,"mm")

Vapor Pressure = 391.0 mm

Example 2 - pg 277

In [2]:
#calculate the change in C values
#Initialization of variables
alpha=4.92*10**-5 #deg**-1
beta=7.85*10**-7 #atm**-1
d=8.93 #g/cm**3
T=298.15 #K
#calculations
dC=63.54*T*alpha**2 *1.987/(d*beta*82.06)
#results
print '%s %.3f %s' %("Change in c values = ",dC," cal/deg mol")

Change in c values =  0.158  cal/deg mol
