What is the K.E. of one mole of a gas at `237^(@)C` ? Given Boltzamann's constant k `= 1.38 xx 10^(-23) J //k`, Avogadro number `= 6.033 xx 10^(23) `.

Text Solution

AI Generated Solution

To find the kinetic energy (K.E.) of one mole of a gas at 237°C, we can use the formula: \[ \text{K.E.} = \frac{3}{2} n k_B T \] where: - \( n \) is the number of moles (which is 1 mole in this case), - \( k_B \) is Boltzmann's constant, - \( T \) is the temperature in Kelvin. ...
