Question

Which of the following equipment is used for the determination of specific gravity of granular agricultural materials?

• A. Distillation unit
• B. Platform scale
• C. Pycnometer
• D. Particle analyzer

Hint:

A pycnometer is used to determine specific gravity or density of granular and powdered materials.

Answer 1

The Correct Option is C

Step 1: Specific gravity is the ratio of the density of a substance to the density of a reference substance. \[ \text{Specific gravity}=\frac{\text{Density of material}}{\text{Density of water}} \]

Step 2: For granular agricultural materials, we need an instrument that can help determine volume and density accurately.

Step 3: A pycnometer is commonly used for determining specific gravity or true density of granular and powdered materials.

Step 4: A platform scale is used only for weighing, not for directly determining specific gravity.

Step 5: A distillation unit is used for separation or purification of liquids, and a particle analyzer is used for particle size analysis.

Step 6: Therefore, the correct equipment is: \[ \boxed{\text{Pycnometer}} \]
