What you understand by thermal analysis.

Thermal analysis refers to a variety of techniques used to study materials as they change with temperature. Here's a step-by-step breakdown of what it involves:

1. Definition: Thermal analysis is a branch of materials science where the properties of materials are studied as they change with temperature.

2. Techniques: Various techniques are used in thermal analysis, including Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Dynamic Mechanical Analysis (DMA), and Thermomechanical Analysis (TMA).

3. Differential Scanning Calorimetry (DSC): This technique measures how much heat is absorbed or released by a sample when it is heated or cooled, providing data on endothermic (heat absorbing) and exothermic (heat releasing) reactions.

4. Thermogravimetric Analysis (TGA): TGA measures the amount and rate of change in the weight of a material as a function of temperature or time in a controlled atmosphere. The measurements provide information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena like chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction).

5. Dynamic Mechanical Analysis (DMA): DMA applies a stress to a material and observes the material’s response as a function of time, temperature, and frequency. This provides information on a material's modulus (stiffness) and damping (energy dissipation) properties.

6. Thermomechanical Analysis (TMA): TMA measures dimensional changes of a material as a function of temperature. These measurements provide valuable information about the material's coefficient of thermal expansion, as well as its contraction, expansion, and deformation behaviors under various conditions.

7. Applications: Thermal analysis has a wide
