Question

For gas samples, most probable speed is $800 m/s$ . The molecules travelling with speed $799 - 800 m/s$ are $N_{1}$ , molecules travelling with speed $899 - 900 m/s$ are $N_{2}$ and molecules travelling with speed $999 - 1000 m/s$ are $N_{3}$ , then

N_{1} > N_{2} > N_{3}

Solution

The correct option is A $N_{1} > N_{2} > N_{3}$
According to Maxwell's distribution law:
The graph is drawn with x-axis as speed and y-axis as number of molecules.

Its clearly evident that $N_{1} > N_{2} > N_{3}$ .

For gas samples, most probable speed is 800 m/s. The molecules travelling with speed 799−800 m/s are N1, molecules travelling with speed 899−900 m/s are N2 and molecules travelling with speed 999−1000 m/s are N3, then

The correct option is A N1>N2>N3According to Maxwell's distribution law: The graph is drawn with x-axis as speed and y-axis as number of molecules. Its clearly evident that N1>N2>N3.
