Synthesis, Dehydration, and Rehydration of .

· Engaging students who are not chemistry majors is a significant challenge. Plaster of Paris is a substance well-known to undergraduate students from early life arts-and-crafts endeavors. Within, a lab is described that connects the synthesis and use of plaster of Paris with a number of chemical principles including stoichiometry, acid–base titration, hydration, and reaction yield.

Fluid and Electrolytes : Principles of Rehydration .

Principles of Rehydration and Fluid Maintenance. The degree of dehydration as graded by clinical characteristics determines the fluid and electrolyte regimen to be used, regardless of the specific etiology. Except for severe dehydration or if the child is not able to tolerate enteral fluids, ...

PRINCIPLES OF DEHIDRATION AND SUN DRYINGPRINCIPLES OF DEHIDRATION AND SUN DRYING The main advantages of dehydration or sun drying over other methods of preservation include : Light weight-between 60% and more than 90% of most foods is water, and most of this is removed by dehydration.The thermal dehydration of synthetic gypsum - .· Mass losses vary between 13.7 and 16.5% and heat of dehydration values between 377 and 420 J g −1 for the dehydration of ground and mixed inhomogeneous gypsum samples. As for the dehydration of CaSO 4 ·2H 2 O, the dehydration of synthetic gypsum proceeds via multi-step reactions. Using a heating rate of 5°C min −1, the very slow dehydration of CaSO 4 ·2H 2 O and impurities in the gypsum ...

Thermo-poro-mechanics Modelling of Gypsum .This paper uses advanced poromechanics to investigate the dehydration of gypsum when subjected to heating. The proposed approach includes the fundamental principles of non-equilibrium thermodynamics as well as the coupled multi-physics of thermal, hydraulic, mechanical and chemical (THMC) processes.
