You have two samples of the same gas in the same size container,with the same pressure.The gas in the first container has a Kelvin temperature four times that of the gas in the other container.
-The ratio of the average velocity of particles in the first container compared to that in the second is
A)1:1
B)4:1
C)1:4
D)2:1
E)1:2

Question

Quizplus · Accepted Answer

The average velocity of gas particles is related to the temperature by the equation $v \propto \sqrt{T}$, where $v$ is the velocity and $T$ is the temperature in Kelvin. If the temperature of the gas in the first container is four times that of the gas in the second container ($T_1 = 4T_2$), then the ratio of their velocities is $\sqrt{4}:1$ or $2:1$.
