Question:
The density that is determined by displacement of helium is known as _____ density.
The density that is determined by displacement of helium is known as _____ density.
Show Hint
Helium gas is preferred for true density determination as it diffuses into fine pores and gives precise solid volume.
Updated On: Jun 16, 2025
- True
- Intrinsic
- Granule
- Bulk
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
True density is measured by gas displacement methods, typically using helium pycnometry, because helium can penetrate even the smallest pores, giving an accurate measurement of the volume occupied by solid material only.
