For example, it takes .417 Joules to raise 1 gram of water 1 degree Celsius. So, water's specific heat is .417 J/C per gram. The specific heat of a material is constant. That means that all pure water has the same specific heat-- .417 J/C. chef hotel transylvania

"WebDifferential scanning calorimetry ( DSC) is the most frequently used thermal analysis technique alongside TGA, TMA and DMA. DSC is used to measure enthalpy changes due to changes in the physical and chemical properties of a material as a function of temperature or time. The method allows you to identify and characterize materials. " - Metal heating water graph
