Question

What is the ideal gas equation?

(a) P=nRT

(b) PV=nRT

(c) PV=ρRT

(d) Pρ=RT

I have been asked this question by my college director while I was bunking the class.

This intriguing question comes from Characteristics of Atmosphere in division Atmosphere and Air Data Measurement of Aircraft Performance

Answer 1

The correct choice is (b) PV=nRT

Explanation: The ideal gas equation is PV=ρRT, where

P=pressure of gas (Units=N/m^2)

V=volume of gas (Units=m^3)

ρ=density of gas (Units=Kg/m^3)

R=universal gas constant (Units=Nm/kg-K)

T=temperature of gas (Units=K).
