Question

Helium gas is in a cylinder that has rigid walls. If the pressure of the gas is 4.00 atm, then the root-mean-square speed of the helium atoms is Vrms = 176 m/s.

By how much (in atmospheres) must the pressure be increased to increase the Vrms of the He atoms by 100 m/s? Ignore any change in the volume of the cylinder.

 

Δp = __________ atm
