Estimate the average thermal energy of a helium atom at (i) room temperature `(27^(@)C)` (ii) the temperature on the surface of the sun (6000K), (iii) the temperature of 10 million kelvin (the typical core temperature in the case of a star)

Explanation

To estimate the average thermal energy of a helium atom at different temperatures, we can use the formula for thermal energy:

\[ E = \frac{3}{2} k T \]

where:
- \( E \) is the thermal energy,
- \( k \) is the Boltzmann constant, approximately \( 1.38 \times 10^{-23} \, \text{J/K} \),
- \( T \) is the temperature in Kelvin.
