1. Curve A represents , gas N2 , because higher the mass of the gas higher will be the peak. This is one of the property of distribution curve.
2. If A and B are same gas at different temperature then , curve A represents the lower temperature. Because , higher the temperature flatter will be the curve . This is also another property of distribution curve.
3. Point A denotes the most probable velocity.
4. Point B denotes the root mean square velocity.
The following picture will describe the points quite well.
NOTE- In the above figure , M1
is greater than M2. And T2 is greater than T1.

3. Most of the atmosphere is made of nitrogen and oxygen. At room temperature, the speed (velocity) of the molecules of N2 and O2 are plotted (horizontal) versus the abundance (amount) of molecules moving at that speed. Identify which gas is represented by which curve (or if both gases would be represented by the same curve), and justify your answer with a brief explanation. (4) venue each element nos Molecular spoed nometer.
