The r.m.s. speed of the molecules of an enclosed gas is x. what will be the r.m.s. speed, if the pressure of the gas is doubled but the temperature is kept constant?
x
2x
As we learnt in
Root mean square velocity -
- wherein
R = Universal gas constant
M = molar mass
P = pressure due to gas
= density
is independent of pressure at a given constant. Hence, final remains the same.
