The average kinetic energy of a gas at \[23{}^\circ C\] and 75 cm pressure is \[5\times {{10}^{-14}}\,erg\] for \[{{H}_{2}}\]. The mean kinetic energy of the \[{{O}_{2}}\] at \[227{}^\circ C\] and 150 cm pressure will be

• A. \[80\times {{10}^{-14}}\,erg\]
• B. \[20\times {{10}^{-14}}\,erg\]
• C. \[40\times {{10}^{-14}}\,erg\]
• D. \[10\times {{10}^{-14}}\,erg\]
