Question
An ideal gas and a solid of the same substance are at the same temperature. The average kinetic energy of the gas molecules is \({E_{\text{g}}}\) and the average kinetic energy of the solid molecules is \({E_{\text{s}}}\). What is the comparison between \({E_{\text{g}}}\) and \({E_{\text{g}}}\)?
A. \({E_{\text{g}}}\) is less than \({E_{\text{s}}}\).
B. \({E_{\text{g}}}\) equals \({E_{\text{s}}}\).
C. \({E_{\text{g}}}\) is greater than \({E_{\text{s}}}\).
D. The relationship between \({E_{\text{g}}}\) and \({E_{\text{s}}}\) cannot be determined.
