Study Notes
Specific Gravity of Gases
- The reference material for measuring specific gravity of gases is air.
Relative Density
- If a substance's relative density is exactly 1, it indicates that the substance has the same density as water.
- If a substance with a relative density less than 1 is placed in water, it will float.
- Relative density is often referred to as specific gravity in non-scientific contexts, but in scientific usage, the preferred term is density.
Density Comparisons
- If a substance's relative density is greater than 1, it is denser than water and will sink if placed in water.
