The correct answer is option (C)
The correct order of temperature is,
T1  < T2 < T3
For a particular speed, the number of molecules having that speed is more at lower temperature than the number of molecules having that speed is more at higher temperature.

Similar Class 11 Doubts

Maxwell Distribution Function In a given mass of gas, the velocities of all molecules are not the same, even when bulk parameters like pressure, volume and temperature are fixed. Collisions change the direction and the speed of molecules. However in a state of equilibrium, the distribution of speeds is constant or fixed. Distributions are very important and useful when dealing with systems containing large number of objects. As an example consider the ages of different persons in a city. It is not feasible to deal with the age of each individual. We can divide the people into groups: children up to age 20 years, adults between ages of 20 and 60, old people above 60. If we want more detailed information we can choose smaller intervals, 0–1, 1–2,..., 99– 100 of age groups. When the size of the interval becomes smaller, say half year, the number of persons in the interval will also reduce, roughly half the original number in the one year interval. The number of persons dN(x) in the age interval x and x + dx is proportional to dx or dN(x) = nx dx. We have used nx to denote the number of persons at the value of x. In a similar way the molecular speed distribution gives the number of molecules between the speeds v and v + dv. dN(v) = 4p N a3 e–bv2v2dv = nvdv. This is called Maxwell distribution.The plot of nv against v is shown in the figure. The fraction of the molecules with speeds v and v + dv is equal to the area of the strip shown. The average of any quantity like v2 is defined by the integralwhich agrees with the result derived from more elementary considerations.Q. When pressure, volume and temperature are fixed, in a given mass of gas, the velocities of all molecules
