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)

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
