In typical solid-state system, ΔgB = −2000 J/mol and γ = 100 mJ/m2 . Calculate the critical size Rc and free energy barrier ΔGc for homogeneous nucleation under these conditions. Assuming that the material is f. c.c. and has a lattice constant of 0.38 nm, how many atoms are there in the critical nucleus? Compare ΔGc to 76kT, assuming a nucleation temperature of 800 K. Is homogeneous nucleation likely under these conditions? (Hint: Read section 19.1.7 of textbook to understand the significance of ΔGc ≈ 76kT for observable nucleation rate)

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
