Question

The density of matter in interstellar space amounts to 1 atom (H not H2) for every cm^3.
(a) What is the pressure of interstellar space assuming a temperature of 4 K?

Answer 1

PV=nRT; n=m/M -> PV=(m/M)*RT -> P=[m/(V*M)]*RT; d=m/V

P=dRT/M

Answer 2

@aaronq I'm not sure I follow? You choose to assume that the hydrogen atom is an ideal gas?

Answer 3

yeah, mainly because the pressure is really low, although the temp is not ideal.

Answer 4

Right. Make since.

Answer 5

(Y) <- thumbs up
