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.
