Molecular speed distribution of Gases Flashcards
1
Q
Heat capacity at constant pressure (Cp)
A
Cp = Cv + R
2
Q
Heat capacities of solids
A
Monatomic crystalline solid of N molecules, each molecule free to vibrate
3
Q
Vmp =
A
most probable
4
Q
Va =
A
average speed
5
Q
The maxwell-Boltzmann distribution
A
f(v) = 4π(m/2πkbT)^(3/2) v^2e^(-mv^2/2kbT)
6
Q
Boltzmann distribution
A
Ratio v/vrms and fraction of molecules with slower speed
7
Q
we have calculated and used vrms in model but, there is a spread of molecular speed
A
can measure this distribution in expt.
f(v) - distribution function or probability.
