Problem

For a monatomic ideal gas, the temperature rises from 250 K to 375 K. Given

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

and

1\,\text{eV}=1.602\times10^{-19}\,\text{J}

, calculate the percent increase in the average kinetic energy PER PARTICLE and express the change in electronvolts.
