Answer:
The final translational rms speed is 247.51 m/s
Explanation:
The translational rms speed, v= 349 m/s.
Translational rms speed of a molecule of an ideal gas is:
- v=[tex]\sqrt{\frac{3KT}{M} }[/tex]
If we keep the pressure and volume of the gas constant,
P1=P2=P and V1=V2=V
while the number of molecules is increased by a factor of 4,
n2=4n1
for constant P, V and R
n1RT1=n2RT2
T2=T1/2
so, final translational rms speed, v2:
- v2=[tex]\sqrt{\frac{3kT2}{M}}[/tex]
v2=[tex]\frac{v1}{\sqrt{2} }[/tex]
substituting values,
v2=349/ sqrt(2)
final translational rms speed:
v2=247.51 m/s
