Question

According to Maxwell's speed distribution law for a gas confined in a container, which of the following statements is/are correct:

• A. All the molecules in the container will have certain non zero speed
• B. Some of the molecules will have zero speed
• C. There will be no molecules travelling with the same speed
• D. Molecules travelling with very high speeds are lesser in number

Answer 1

Answer: (A), (D)

The correct options are
A All the molecules in the container will have certain non zero speed
D Molecules travelling with very high speeds are lesser in number

According to graphical representation of Maxwell's speed distribution law:
There will be no molecules with zero speed, as you can see the graph starts on x-axis with non zero value.
Number of molecules travelling at a specific speed will vary depending upon the speed; there will be less molecules for higher speeds. Hence, there are molecules travelling with the same speed.
