Answer :
Answer: The average kinetic energy of helium atoms is [tex]1.222\times 10^{-17}J[/tex]
Explanation:
To calculate the average kinetic energy of the atom, we use the equation:
[tex]K=\frac{3}{2}kT[/tex]
where,
K = average kinetic energy = ?
k = Boltzmann constant = [tex]1.3807\times 10^{-23}J/K[/tex]
T = temperature = [tex]5.9\times 10^5K[/tex]
Putting values in above equation, we get:
[tex]K=\frac{3}{2}\times 1.3807\times 10^{-23}J/K\times 5.9\times 10^5K\\\\K=1.222\times 10^{-17}J[/tex]
Hence, the average kinetic energy of helium atoms is [tex]1.222\times 10^{-17}J[/tex]
