Q.
The effect of temperature on Maxwell’s speed distribution is correctly shown by
Kinetic Theory
Solution:
The Maxwell's distribution curve heats at the most probable speed, which depends on temperature.
$v_{\text {probabble }} \propto \sqrt{T}$
Hence $T_{1} >T_{2}$ is correctly shown in option (1) as it shows with peaks of the curve at higher temperature, furthers along the $x$-axis.
