Explanation:
Let [tex]T[/tex] be the temperature in kelvin.
Let [tex]KE[/tex] be the average kinetic energy.
Let [tex]n[/tex] be the number of moles.
Let [tex]R[/tex] be the universal gas constant.
As we know,
[tex]KE=\dfrac{3}{2}nRT[/tex]
Given,
[tex]n=1\\T=273-32=241K[/tex]
we know that [tex]R=8.314JK^{-1}mol^{-1}[/tex]
So,[tex]KE=\frac{3}{2} \times 1\times 8.314\times 241=3005.5J[/tex]=[tex]3.01\times 10^{3}J[/tex]
