The energy barriers for the two main types of this process differ by the multiplicative factor “2, minus 3 cosine theta, plus cosine cubed theta, all over 4.” (15[1])The change in volume Gibbs free energy is inversely proportional to the critical radius for this process; (15[1])objects smaller than that radius fail to undergo (15[1])this process and are called “embryos.” (15[1])On (15[1])a specific S-shaped graph of heat flux vs temperature, (15[1])the “transition” regime separates the “film” regime from a regime named for this (15[1])process. Because the (*) heterogeneous form of this process is more efficient, many “sites” for this process (-5[1])are provided by Teflon-coated (10[1]-5[1])calcium carbonate chips (-5[1])to facilitate (-5[2])calm (-5[1])boiling. (10[3])For 10 points, (10[1])name (10[1])this first step (10[1])in the formation (10[1])of a new phase, (10[1])exemplified by formation (10[1])of bubbles in a heated liquid. (10[1])■END■ (10[3]0[1])
