Question

if p is pressure and p the density of a gas then p and p are related to

Answer 1

Answer:

ρ = p R-1 T-1

Explanation:

The Ideal Gas Law for dry air:

pV = RT

where:

p = air pressure (hPa) (kg m-1 s-2)

V = air volume (m3)

R = universal gas constant for dry air (287 J kg-1 K-1)

T = air temperature (K)

For atmospheric applications, however, volume is not well defined, and since density is mass per volume, using atmospheric mass and volume, the Gas Law can be reformulated:

p = ρRT where ρ = air density

Therefore

ρ = p R-1 T-1
