Question

helium and hydrogen gas are at an unknown ambient temperature, x. given this information, fill in the blanks below. simplify your answers whenever possible. write any numbers with three significant figures

Answer 1

Hydrogen and helium are the lightest elements in the periodic table.

What is helium and hydrogen made of?

• Hydrogen and helium are uniformly mixed and form a layer on the surface of gas giants.

• Scientists predicted in the 1970s that the two lightest elements might separate and form a region of demixing or immiscibility at the high temperatures and pressures found inside gas giants.

• They are the two most prevalent elements in the universe and are gases at room temperature, with hydrogen constituting roughly 75% of all matter.

• A helium atom consists of a nucleus with two neutrons and two positively charged protons, which is surrounded by two negatively charged electrons in orbit.

• One proton and one electron make up one hydrogen atom.

translational = 3

rotational = 2

vibrational = 1

Total = 6

Internal energy = 6N  x 1 /2 k T where N is no of molecules

E₁ = 3 N kT

At the temperature of 1000K , helium  will have following degree of freedom

translational = 3

rotational = 0

vibrational =  0

Total = 3

Internal energy = 3N  x 1 /2 k T where N is no of molecules

E₂ = 3 / 2 N kT

Ratio =  E₁ / E₂

=  2
