What does the onset temperature in a thermogravimetric analysis (TGA) curve indicate?
- The temperature at which the sample starts to decompose
- The temperature at which the sample reaches its maximum weight
- The temperature at which the sample completes its decomposition
- The temperature at which the sample melts
Explanation
The onset temperature in a thermogravimetric analysis (TGA) curve indicates the point at which a material starts to experience a significant mass loss due to:
- Thermal events such as decomposition,
- Evaporation of volatiles
- Or the initiation of reactions
This temperature serves as an important measure of a material's thermal stability, although it can be influenced by factors like heating rate, sample size, and atmosphere.
