Which of the fields below are significantly involved in food engineering?
A. Civil engineering, structural engineering, genetic engineering
B. Construction technology, civil engineering, structural
engineering
C. Biology, industrial engineering civil engineering
D. Genetic engineering, chemical engineering, biology

D.

Explanation:

Genetic Engineering is a huge part in manipulating a foods property. Chemical engineering mostly the science with numbers in foods.

Biology is literally the life of the food.

0.74°C

Explanation:

The freezing point depression is a colligative property that can be calculated using the following expression.

ΔTf = Kf . b

where,

ΔTf: depression in the melting point

Kf: freezing point depression constant

b: molality

The mass of the solvent (benzene) is:

The moles of solute (naphtalene) are:

The molality of naphtalene is:

ΔTf = Kf . b

ΔTf = (4.90°C/m) . 0.972m = 4.76°C

The melting point of the solution is:

5.50°C - 4.76°C = 0.74°C
