Cabalistic Rheological & Thermodynamically Characteristics of Some Naturals Dyes (Experiment for Undergraduate Students)

Mysterious puissance of temperature on rheology and thermodynamics were studied on three natural Dyes. The flowing property of all Dyes was also examined at a constant temperature that was 25±1ºC. Randomness was observed in viscosity at a constant temperature with the variation in concentration. At varying temperatures, the activation energy of Rubus laciniatus and Cinnamon Bark Dyes were in negative form indicate that the less probability of collision between the molecules of Dyes. Chances of arrangement of all Dye molecules are in high order. The activation energy of Purple Cabbage was positive integer while the Gibbs energy of all Dyes was in a negative form which divulgement that the reaction of Dyes was spontaneous. The statistical treatment was also performed on Viscosity data. Trimmed and winsorized measurement examined outliers of viscosity data.
