The specific gravity of tar ranges from-
-
A.
1.1 to 1.25
-
B.
3.15 to 3.5
-
C.
2.7 to 2.8
-
D.
4 to 5
Correct Answer:
A. 1.1 to 1.25
Explanation:
The specific gravity of tar typically falls between 1.1 and 1.25. This value is a measure of its density relative to water and is an important characteristic used to identify the quality and type of coal tar or wood tar in construction and industrial applications. Tar is denser than water, which is why it sinks rather than floats.
