Heating to constant mass definition
WebThermal gravimetric analysis (TGA) is a method of thermal analysis in which changes in physical and chemical properties of materials are measured as a function of increasing temperature (with constant heating rate), or as a function of time (with constant temperature and/or constant mass loss). WebThe specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). Calculating thermal energy changes The …
