Definition

1. Adjective:
   • Relating to thermogravimetry: Pertaining to a technique that measures the change in mass of a substance as its temperature changes.
   • Involving the measurement of weight changes under controlled temperature: Describing an analytical process where a sample's mass is continuously recorded while it is heated or cooled in a controlled manner.

Usage Examples

• Adjective:
  • The researchers performed a thermogravimetric analysis to determine the polymer's thermal stability.
  • The thermogravimetric curve showed a significant weight loss at 300°C.

Advanced Usage

• "Thermogravimetric analysis (TGA)": A specific analytical technique that is the primary application of the adjective.
  • Thermogravimetric analysis is essential for studying the decomposition kinetics of materials.

Variants and Related Words

• Thermogravimetry (n): The technique or field of study itself.
  • Thermogravimetry provides valuable data on material composition.
• Thermogravimetrically (adv): In a manner relating to thermogravimetry.
  • The sample was analyzed thermogravimetrically.

Synonyms

• Thermal gravimetric: An alternative phrasing with the same meaning.
• Mass-loss under heating: A descriptive phrase for the process measured.

Notes on Different Meanings

• The term is highly specialized and used almost exclusively in scientific contexts, particularly in chemistry, materials science, and thermal analysis. It does not have common idiomatic or figurative uses. The reference to "thermal hydrometry" in the provided context appears to be an error or a very niche application; the standard and primary definition relates to measuring mass change versus temperature.
