gravimetry
/grə'vimitri/
Definition
Noun: 1. The measurement of specific gravity: The scientific process of determining the relative density of a substance, often a liquid or solid, by comparing its weight to the weight of an equal volume of water. 2. The measurement of gravitational fields: In geophysics and related fields, the practice of measuring variations in the Earth's gravitational field to study subsurface structures.
Examples of Usage
- Chemistry/Physics Context:
- The gravimetry of the mineral sample revealed its high purity.
- Accurate gravimetry is essential for determining the concentration of solutions.
- Geophysics Context:
- Scientists used gravimetry to map the underground density variations.
- Aerial gravimetry surveys help in mineral and oil exploration.
Advanced Usage
- "Gravimetric analysis": A precise analytical chemistry technique where the amount of a substance is determined by measuring the mass of a pure compound containing that substance. This is a primary application of gravimetry in a laboratory setting.
- The sulfate content was quantified through gravimetric analysis.
Variants and Related Words
