Given is the graph between \( \frac{P V}{T} \) and \( P \) for \( 1 \mathrm{~g} \) of oxygen gas at two different temperatures \( T_{1} \)
\( \mathrm{P} \) and \( T_{2} \), as shown in figure. Given, density of oxygen \( =1.427 \mathrm{~kg} \mathrm{~m}^{-3} \). The value of \( P V / T \) at the point \( A \) and
W. the relation between \( T_{1} \) and \( T_{2} \) are respectively
(a) \( 0.259 \mathrm{~J} \mathrm{~K}^{-1} \) and \( T_{1}T_{2} \)
(b) \( 8.314 \mathrm{~g} \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1} \) and \( T_{1}T_{2} \)
(c) \( 0.259 \mathrm{~J} \mathrm{~K}^{-1} \) and \( T_{1}T_{2} \)
(d) \( 4.28 \mathrm{~g} \mathrm{~J} \mathrm{~K}^{-1} \) and \( T_{1}T_{2} \)
