Moderate

Molecular Speed: Heating at Constant Volume

APPH12-KKGEYB

Heat is quickly added to an enclosed cylinder of gas so that the pressure increases from $1.0\text{ atmosphere}$ to $3.0\text{ atmospheres}$. The volume of the cylinder is kept constant.

What happens to the rms speed of the gas molecules after this addition of heat?

A

Increases by a factor of $\sqrt{ 3 }$.

B

Increases by a factor of $3$.

C

Increases by a factor of $9$.

D

The rms speed is not related to the pressure of the gas.
