(b) Energy required is indirectly proportional to the increase in surface area

(c) Pressure required is directly proportional to the increase in surface area

(d) Pressure required is indirectly proportional to the increase in surface area

The question was asked in homework.

The origin of the question is Size Reduction topic in section Size Reduction of Food Processing Unit Operations

Answer 1

Right choice is (a) Energy required is directly proportional to the increase in surface area

To elaborate: The Rittinger’s law is stated as the energy required for reduction in particle size of a solid is directly proportional to the increase in surface area.
