A helium atom is in a nanowire (a wire with a diameter on the scale of molecules)

Question:

A helium atom is in a nanowire (a wire with a diameter on the scale of molecules) in thermal equilibrium at $77 \mathrm{~K}$.

(a) The atom is constrained in the nanowire and so can move in only one dimension, along the wire length. What is the atom's thermal energy?

(b) The atom is boiled off the nanowire and allowed to float free at $295 \mathrm{~K}$. What is its thermal energy now?
