Question

What is Bond’s law?

(a) Work required is directly proportional to the surface to volume ratio

(b) Work required is indirectly proportional to the surface to volume ratio

(c) Energy required is directly proportional to the surface to volume ratio

(d) Energy required is directly proportional to the surface to volume ratio

I got this question in an interview.

This intriguing question comes from Size Reduction in section Size Reduction of Food Processing Unit Operations

Answer 1

Right option is (a) Work required is directly proportional to the surface to volume ratio

Easiest explanation: Bond’s law states that the work required to produce particles from large particle size is directly proportional to the square root of the surface-to-volume ratio.
