Physics

Two copper cylinders, immersed in a water tank at 46.3°C contain helium and nitrogen, respectively. The helium-filled cylinder has a volume twice as large as the nitrogen-filled cylinder.

a) Calculate the average kinetic energy of a helium molecule at 46.3°C.

b) Calculate the average kinetic energy of a nitrogen molecule at 46.3°C.

c) Determine the molar specific heat at constant volume (CV) and at constant pressure (Cp) for helium. Enter CV first. Give answer in J/mol·K.

d) Determine the molar specific heat at constant volume (CV) and at constant pressure (Cp) for nitrogen. Enter CV first. Give answer in J/mol·K.

e) Find γ for helium.

f) Find γ for nitrogen.

  1. c) Cv=(3*R)/2=12.465 J/mol*K
    Cp=((3+2)*R)/2=20.775 J/mol*K

    d) Cv=(5*R)/2=20.775 J/mol*K
    Cp=((5+2)*R)/2=29.085 J/mol*K

    e) γHe=Cp/Cv=1.66

    f) γN=Cp/Cv=1.4
