PV versus T graph of equal masses of $H_{2}$ , He and $CO_{2}$ is shown in figure. Choose the correct alternative.

Options:

Answer:

Solution:

$\frac{P V}{T} = n R$ , so slope $\propto$ number of moles $\propto \frac{1}{M}$ for equal masses. $M : H_{2} = 2 < He = 4 < CO_{2} = 44$ , so slope: line $3 = H_{2}$ , line $2 = He$ , line $1 = CO_{2}$ .
