SUMMARY
The discussion centers on the relationship between the number of gas molecules and the root mean square (RMS) speed in an isothermal process. It is established that while the average kinetic energy remains constant at a given temperature, halving the mass of the molecules results in a doubling of the RMS speed, as indicated by the equation m1(v1)² = m2(v2)². Specifically, if m2 equals m1/2, then v2² equals 2v1², confirming the direct correlation between mass and speed in gas behavior.
