Chapter 15 - Ideal gases

Question 1

What do the letters stand for in pV=nRT?

Answer 1

Pressure x volume = number of moles x molar gas constant x temperature

Question 2

What do the letters stand for in pV=NkT?

Answer 2

Pressure x volume = number of gas molecules x Boltzmann constant x temperature

Question 3

What do the letters stand for in

pV=(1/3)Nm(C bar ^2)?

Answer 3

Pressure x volume = (1 divided by 3) x number of gas molecules x mass x C bar ^2

Question 4

What does the letters stand for in 1/2 x m x (c bar ^2) = 3/2 x k x T?

Answer 4

1/2 x mass x speed of light = 3/2 x Boltzmann constant x temperature
KE = 3/2 x Boltzmann constant x temperature

Question 5

What equation can we use to derive 1/2 x m x (C bar ^2) = 3/2 x k x T?

Answer 5

E = 3/2 x k x T

because KE = 1/2 m c^2
