What is the relation between the vapour temperature and the liquid temperature on nucleation for a bubble inside the fluid?

A. T<sub>v</sub> T<sub>sat</sub> = (2 /r p<sub>g</sub>) R<sub>v</sub> T<sub>v</sub>/p<sub>v</sub> h<sub>fg</sub>
B. T<sub>v</sub> T<sub>sat</sub> = (2 /r p<sub>g</sub>) R<sub>v</sub> T<sub>v</sub><sup>2</sup>/p<sub>v</sub> h<sub>fg</sub>
C. T<sub>v</sub> T<sub>sat</sub> = (2 /r p<sub>g</sub>) R<sub>v</sub> T<sub>v</sub><sup>2</sup>p<sub>v</sub> h<sub>fg</sub>
D. T<sub>v</sub> T<sub>sat</sub> = (2 p<sub>g</sub>) R<sub>v</sub> T<sub>v</sub><sup>2</sup>/p<sub>v</sub> h<sub>fg</sub>
Answer» C. T<sub>v</sub> T<sub>sat</sub> = (2 /r p<sub>g</sub>) R<sub>v</sub> T<sub>v</sub><sup>2</sup>p<sub>v</sub> h<sub>fg</sub>
