Study Notes
Volume of the Sample
- The volume of the sample is determined through measurement techniques which can include water displacement.
Formula for Density
- Density is calculated using the formula: Density = Mass / Volume.
Density of the Sample
- The density of the sample is given in grams per cubic centimeter (grams/cc).
Calculation of Specific Gravity
- Specific gravity is calculated by comparing the density of a substance to the density of water at 4°C.
Specific Gravity of the Sample
- The specific gravity of the sample is a dimensionless number indicating its density relative to water.
Specific Gravity of Materials
- The specific gravity of gold is approximately 19.3.
- The specific gravity of quartz is around 2.65.
- The specific gravity of graphite is about 2.2.
Definition of Density
- Density refers to the mass per unit volume of a material.
Definition of Specific Gravity
- Specific gravity is defined as the ratio of the density of a substance to the density of a reference substance, usually water.
Sinking Property of a Brick
- A brick sinks in water because its density is greater than that of water.
First Step in Measuring Density
- The first step in measuring the density of a mineral specimen involves accurately determining its mass.
Relationship Between Specific Gravity and Mineral Density
- Specific gravity provides a direct comparison of mineral density to that of water, helping identify mineral types.
Variation in Specific Gravity Among Minerals
- Different minerals have varying specific gravities due to differences in composition, atomic structure, and arrangement.
Property Used to Describe Density
- Mineralogists use specific gravity as a property to characterize the density of minerals.
