Brinell Hardness Number (BHN) for talc is approximately in the range of
A. 1-5
B. 20-30
C. 100-150
D. 200-250
Answer: Option A
Solution (By Examveda Team)
Brinell Hardness Number (BHN) is a measure of the hardness of materials, with higher values indicating harder materials.Talc is a soft mineral, often used in cosmetics and as a lubricant.
The BHN of talc is very low, typically falling within the range of 1-5, indicating its softness compared to other materials.
