Ch. 3 Equations

Question 1

Avg. KE of gas particles, given 3 degrees of freedom

Answer 1

3/2 kT (k = Boltzmann’s constant)

Question 2

Microscopic scale version of PV = nRT

Answer 2

PV = NkT (total no. of particles x Boltzmann constant x temperature)

Question 3

1 cm^3 = how many m^3?

Answer 3

1 cm = 10^-6 m^3

Question 4

k (Boltzmann’s constant) in terms of other constants

Answer 4

k = R/NA (gas constant/Avogadro’s number)
