Vedclass · Answer

(B) The kinetic energy of $1$ mole of an ideal gas is given by the formula $K.E. = \frac{3}{2}RT$.Here,$R$ is the universal gas constant,$R = 8.314 \, J \cdot mol^{-1} \cdot K^{-1}$ (often approximated as $8.3 \, J \cdot mol^{-1} \cdot K^{-1}$ in calculations).The temperature $T$ in Kelvin is $T = 27 + 273 = 300 \, K$.Substituting the values: $K.E. = \frac{3}{2} 	imes 8.3 	imes 300$.$K.E. = 1.5 	imes 8.3 	imes 300 = 3735 \, J$.
