Question

The angle of repose is primarily used to determine ____.

• A. particle density
• B. flowability of powders
• C. surface charge
• D. particle solubility

Hint:

A small angle of repose means better flow. This parameter is critical in tablet manufacturing and powder filling.

Answer 1

The Correct Option is B

The angle of repose is the steepest angle at which a pile of unconsolidated powder remains stable. It indicates how easily a powder flows—lower angles suggest better flow properties.
