The following graph is obtained for a gas at different temperatures $\left(\mathrm{T}_1, \mathrm{~T}_2, \mathrm{~T}_3\right)$. What is the correct order of temperature $（x$-axis $=$ velocity; $y$-axis $=$ number of molecules)
$\mathrm{T}_2 \gt \mathrm{T}_1 \gt \mathrm{T}_3$
$\mathrm{T}_2 \gt \mathrm{T}_3 \gt \mathrm{T}_1$
$T_3 \gt T_1 \gt T_2$
$\mathrm{T}_3 \gt \mathrm{T}_2 \gt \mathrm{T}_1$
Solution
According to Maxwell - Boltzmann distribution of molecular speeds, $T_2 \gt T_1 \gt T_3$.
