Thermogravimeter - English Definition & Meaning

Definition

A thermogravimeter is an instrument that measures the change in weight of a substance as a function of temperature or time. It's used in thermal analysis to study the thermal stability and composition of materials. The sample is heated or cooled in a controlled atmosphere, and the weight changes are continuously recorded. Imagine it as a super-sensitive scale that reacts to heat. This provides information about decomposition, oxidation, and other thermal processes.

Etymology

The word 'thermogravimeter' combines 'thermo' (heat), 'gravi' (weight), and 'meter' (measure). 'Thermo-' is derived from the Greek 'thermos,' meaning hot. 'Gravi-' comes from the Latin 'gravis,' meaning heavy. 'Meter' is from the Greek 'metron,' meaning measure. Therefore, it is a device that measures weight changes due to heat.
