Thermal analysis is a branch of materials science where the properties of materials are studied as they change with temperature. Several methods are commonly used - these are distinguished from one another by the property which is measured:
Differential thermal analysis (DTA): temperature difference
Differential scanning calorimetry (DSC): heat difference
Thermogravimetric analysis (TGA): mass
Thermomechanical analysis (TMA): dimension
Dilatometry (DIL): volume
Dynamic mechanical analysis (DMA) : mechanical stiffness & damping
Dielectric thermal analysis (DEA): dielectric permittivity & loss factor
Evolved gas analysis (EGA) : gaseous decomposition products
Thermo-optical analysis(TOA) : optical properties
