Web(Well, not quite half: some energy is used dissociating H2 molecules and then ionizing the gas.) Going back to the virial theorem, U = −1 2 Ω , we see we have an estimate for the average thermal energy of the Sun: U ∼ 2 × 1048 erg. Dividing by the Sun’s volume, V⊙ = 4 3 πR⊙ 3 = 1.41×1033 cm3, the energy per unit volume is < u ⊙ ... WebThe total internal energy of a system is the sum of the kinetic and potential energies of its atoms and molecules. Thermal energy is one of the subcategories of internal energy, as is chemical energy. To measure temperature, some scale must be used as a standard of measurement. The three most commonly used temperature scales are the Fahrenheit ...

WebAt temperature, T = 10 7 K. Average thermal energy `= 3/2` kT `= 3/2 xx 1.38 xx 10^(-23) xx 10^7` = 2.07 × 10 –16 J. Hence, the average thermal energy of a helium atom at …
Weband its thermal energy is E th = 3 2 NkT. (3.24) Thus, P = 2 3 E th V, (3.25) i.e., the local pressure equals 2/3 the local thermal energy density. Multiplying both sides by 4πr2 and integrating over the volume of the star, we find that PV¯ = 2 3 Etot th, (3.26) with Etot th the total thermal energy of the star. Substituting from Eq. 3.22 ... WebEstimate the average thermal energy of a helium atom at: (i) room temperature (27°C), (ii) the temperature on the surface of the sun (6000°K), (iii) the temperature of 10 million degree Kelvin (the typical core temperature in the case of a star) k = 1.38x10 2–3 J/K.
Webatoms are transformed into one helium atom. The result of this process is not only a helium atom, but considerable energy. #8. Using the mass and size of the Sun, calculate the Sun’s average density. Compare to the average density of Earth and the outer planets. The volume of a sphere is (4/3)πr3. Mass of the Sun: 2.0 x 1033 gm
