A metallic body whose specific gravity matches the fluid it is placed in (specific gravity a) will____________________?
Show answer Hide answer
Answer: D. be fully immersed with top surface at fluid surface
Explanation
Equal specific gravity means the object and fluid share identical densities throughout their respective volumes. Neutral buoyancy causes the object neither to sink downward nor to float upward toward the air. The body remains fully immersed with its top surface perfectly aligned with the fluid surface boundary. Specific gravity is the ratio of the density of a substance to the density of pure water. Objects with lower specific gravity than the fluid will float partially above the liquid surface line. Objects with higher specific gravity than the surrounding fluid will sink completely to the bottom.
Sinking to the bottom only occurs when the object has a higher specific gravity than the fluid. Floating over the fluid requires the object to possess a significantly lower specific gravity value. Partial immersion happens when the body density is lower than the supporting fluid density.
