      My ans: 100 Driving force for sintering is inversely proportional to the surface area [∆G proportional to 1/(R^2)]. (∆G1)÷(∆G2)=(R2÷R1)^2 ∆G2=100∆G1 Corrections are welcomed and thanked.

      My ans: 100

      Driving force for sintering is inversely proportional to the surface area [∆G proportional to 1/(R^2)]. (∆G1)÷(∆G2)=(R2÷R1)^2

      ∆G2=100∆G1

      Corrections are welcomed and thanked.
