Problem

In a sample of material at absolute temperature,

T

, the average random speed of atoms is

500\text{ ms}^{-1}

. If the temperature of the same sample is doubled to

2T

, which of the following is the best estimate of the average random speed of the atoms? a.

250\text{ ms}^{-1}

500\text{ ms}^{-1}

700\text{ ms}^{-1}

1000\text{ ms}^{-1}
