Estimate the average thermal energy of a helium atom at (i) room temperature (27°C), (ii) the temperature on the surface of the sun (600 K), (iii) the temperature of 10 million kelvin (the typical core temperature in the case of a star.)

||☆☆Answer☆☆||

Hence, the average thermal energy of a helium atom at room temperature (27°C) is 6.21 × 10–21 J. Hence, the average thermal energy of a helium atom on the surface of the sun is 1.241 × 10–19 J. Hence, the average thermal energy of a helium atom at the core of a star is 2.07 × 10–16 J.
