Question

Boltzmann constant k=1.38×10^-23 j/k the energy associated with helium atom at the surface of the sun where surface temperature is 6000 k is

Answer 1

Answer: $E = 1.24\times10^{-19} J$

Explanation:

Given that,

Boltzmann constant $k = 1.38\times 10^{-23} J/K$

Temperature T = 6000 K

We know that,

The Kinetic energy of a molecule is direct proportional to the temperature of the surface.

The energy is

$E = \dfrac{3}{2}kT$

$E = \dfrac{3}{2}\times 1.38\times10^{-23}J/K\times 6000 K$

$E = 1.24\times10^{-19} J$

Hence, the energy associated with helium atom at the surface of the sun is $E = 1.24\times10^{-19} J$.

Answer 2

The ideal gas law can be written in terms of the number of molecules of gas: PV = NkT, where P is pressure, V is volume, T is temperature, N is number of molecules, and k is the Boltzmann constant k = 1.38 × 10–23 J/K. A mole is the number of atoms in a 12-g sample of carbon-12.
