Match each measurement in List I with the instrument or method in List II.
List I
A. Moisture content
B. Terminal velocity
C. Colour
D. Viscoelastic behaviour
List II
1. Vertical air column with variable fan
2. Oven drying and weighing
3. Universal testing machine in relaxation mode
4. Hunter or CIE colorimeter
Select the correct match.
Answer: C
Correct answer: A-2, B-1, C-4, D-3
Each measurement has one standard method. Moisture content is determined by oven drying and weighing - the reference procedure against which every meter is calibrated.
Terminal velocity is found in a vertical air column with a variable fan, by raising the air speed until the particle is just suspended. Colour is read on a Hunter or CIE colorimeter as the coordinates \( L \), \( a \) and \( b \). Viscoelastic behaviour is obtained on a universal testing machine in relaxation mode, holding a fixed deformation and recording the force as it decays.
