If the molecules in the two cylinders have same rms speeds, find the false statements.
Answer to Problem 1OQ
Option (c)
Explanation of Solution
Write the expression for rms speed of the oxygen gas molecules.
Here,
Similarly the expression for rms speed of the nitrogen gas molecules
Here,
Molecules in both the cylinders have same rms speed.
Equate (I) and (II).
Conclusion:
Rearrange the equation (III) for
If mass of the nitrogen gas is less than the oxygen gas (
If the above ratio is keep same as the molar mass of the two different gases, meanwhile temperature is also different. Therefore, option (a) is True.
If mass of the nitrogen gas is greater than the oxygen gas (
Average kinetic energy depend on temperature so if
