Problem

The average kinetic energy of a gas molecule is measured to be

6.21\times10^{-21}\,\text{J}

. Using

k = 1.38\times10^{-23}\,\text{J K}^{-1}

, determine the temperature of the gas. a)

4.5\times10^{2}\,\text{K}

6.75\times10^{2}\,\text{K}

3.0\times10^{2}\,\text{K}

9.0\times10^{2}\,\text{K}
