Question
A one dimensional gas is a hypothetical gas with molecules that can move along only a single axis. The following table gives four situations, the velocities in meter per second of such a gas having four molecules. The plus and minus sign refer to the direction of the velocity along the axis.
In which situation root-mean-square speed of the molecules is greatest
In which situation root-mean-square speed of the molecules is greatest
Options
A.a
B.b
C.c
D.d
Solution
Using Vrms = 
and substituting the corresponding velocity we get Vrms is greatest in situation b.
and substituting the corresponding velocity we get Vrms is greatest in situation b.
