Q1. The Accelerated Storage Test Of Food Can Be Done By?

A. Fick’s Model
B. Arrhenius Model
C. Kirchhoff’s Model
D. Stefan-Boltzmann

ANSWER: B. Arrhenius Model

• Explanation: Accelerated Shelf-Life Testing (ASLT) Method, Arrhenius Model, Is Widely Used For Predicting The Shelf Life Of Perishable Food. The Shelf Life Of Food Products May Be Determined By The Arrhenius Models, I.E: Canned Food, Fruit Juice, Instant Mix, Frozen Meat And High-Fat Product (Fat Oxidation), Products That Contain Reducing Sugar And Protein (Browning Reaction ). The Accelerated Storage Test Of Food Can Be Done By Arrhenius Model.

Q2. CGS Unit Of Viscosity Is?

A. Poise
B. Pascal Second
C. Pascal Meter
D. None Of The Above

ANSWER – A. Poise

• Explanation– Poise Is The CGS Unit Of Viscosity, Equivalent To Dyne-Second Per Square Centimeter. It Is The Viscosity Of A Fluid In Which A Tangential Force Of 1 Dyne Per Square Centimeter Maintains A Difference In Velocity Of 1 Centimeter Per Second Between Two Parallel Planes 1 Centimeter Apart.

Q3. Tomato Ketchup Is An Example Of?

A. Non- Newtonian Fluids
B. Newtonian Fluids
C. Plastic Fluids
D. Both B And C

ANSWER – A. Non- Newtonian Fluids

• Explanation- Ketchup Is A Non-Newtonian Fluid Because, Unlike Water, Its Viscosity Is Dependent On Shear Rate. It Is Pseudoplastic (Shear-Thinning), A Type Of Non-Newtonian As When Force Is Applied, The Liquid Viscosity Thins In Ketchup. Ketchup Is Known As A Casson Plastic, Meaning It Has A Non-Linear Flow Once The Critical Stress Point Is Overcome.

Q4. Centrifuges Used For Solid-Liquid Separation Are Called?

A.  Clarifiers
B. Separators
C. Purifiers
D. Polishers

ANSWER: A. Clarifiers

• Explanation: A Clarifier Is A Solid-Liquid Separator That Separates Solids Such As Particles, Sediments, Oil, Natural Organic Materials, And Colour From Process Liquids Using Centrifugal Force. The Process Liquid Becomes Clear As A Result Of This.

Q5. ______________ Is A Property Of Fluid Which Represents The Resistance Of Fluid To Shearing Action?

A. Pressure
B. Viscosity
C. Gravity
D. Density

ANSWER -B. Viscosity

• Explanation  –  Viscosity Is A Fluid Property That Controls A Fluid’s Resistance To Shear Stresses Or Resists Relative Motion Between Layers. Viscosity Characterizes How Strongly A Fluid Resists Shearing Motion.
