Crystalline solids have smooth cooling curve
Webincrease in the viscosity of the fluid. Materials that show cooling curves of the type shown in Figure 4.1(a) change during cooling from true fluids, through stages of steadily increasing viscosity, into an apparently solid condition. The atoms or molecules present still have the same type of random arrangement that existed in the true fluid state. WebDifferential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. Generally, the …
