Question

P-T diagram of an ideal gas having three different densities ρ 1 ​ , ρ 2 ​ , ρ 3 ​ (in three different cases) is shown in the figure. Which of the following is correct :

TestHub · Accepted Answer

For ideal gas ​ P V = n RT P V = M m ​ RT P = ( V M ​ ) M RT ​ P = M ρRT ​ ​ (Where m is mass of gas and M is molecular mass of gas) for same temperature P 1 ​ > P 2 ​ > P 3 ​ So ρ 1 ​ > ρ 2 ​ > ρ 3 ​
