Question

Figure shows graphs of pressure vs density for an ideal gas at two temperature $T_{1}$ and $T_{2} .$ Which of the following is correct?

• A. $T_{1} >T_{2}$
• B. $T_{1}=T_{2}$
• C. $T_{1} < T_{2}$
• D. any of the three is possible

Answer 1

Answer: (A)

For a constant value of density, pressure is more at $T_{1}$.
$\therefore T_{1}>T_{2} [\because P \propto T]$
