Which parameter is used for the grading of paraffin waxes?
A. Specific gravity
B. Melting point
C. Viscosity
D. Penetration number
Answer: Option B
Solution (By Examveda Team)
The grading of paraffin waxes is primarily based on their melting point.The melting point is a critical parameter because it determines the temperature at which the wax transitions from a solid to a liquid state.
Different applications require paraffin waxes with specific melting points to ensure proper performance.
Therefore, Option B: Melting point is the correct answer.
