thermic analysis

Thermal analysis is a chemistry technique used to study how substances change when heated. It involves monitoring a property of the substance, often its temperature, as heat is added. By observing how the temperature changes compared to an inert material, scientists can identify chemical changes or phase transitions that involve absorbing or releasing heat.123

This method is useful for both qualitative and quantitative analysis, helping to identify substances and determine their amounts. For example, compounds containing water will show a constant temperature region as the water is removed, even while heat is continuously applied. Differential thermal analysis (DTA) is a specific type where the test material's temperature is compared to an inert material's temperature, recording differences as peaks on a graph. This technique is widely used for identifying minerals.23
