Thermogravimetric curve is to be determined from the given mass and melting point. Concept introduction: Thermogravimetric curve is a plot ofthe percentage of mass and temperature, comprising of a progression of a numbers of steps, acquired by estimating the mass of a sample during heating. It is a strategy used for heat calculation where the mass of a sample is estimated after some time as the temperature changes.
