Thermodynamic Modeling: A Unique Tool to Study Magmatic Systems Nikitha Susan Saji Given a set of variables - temperature‚ pressure and concentrations of chemical components forming the system – thermodynamic theory has the rigorous theoretical framework that can simulate chemical evolution of magmatic systems. This is what thermodynamic modeling does. Equilibrium phase composition of the system is calculated as a function of existing conditions. This article primarily explains the theory and method

In this experiment we investigate the properties of SLIME. Substitution of polyvinyl alcohol instead of Guar gum makes this experiment quite accessible. The Slime is prepared by mixing a solution of (Na2B4O7*10H2O) sodium tetraborate decahydrate (Borax) and H2O with a solution of polyvinyl alcohol (pva) and H2O. Then stirring for ~10 minutes to obtain the final product‚ SLIME. The product was examined and noted on the “non-Newtonian fluid” properties. Object The object of this lab is to become

recipes for slime with different characteristics. 2. The slime is made by preparing two separate solutions‚ which are then mixed. You can double‚ triple‚ etc. the recipe if you want more slime. The ratio is 3 parts PVA or glue solution to 1 part borax solution‚ with a little glow-in-the-dark agent thrown in (measurement isn’t critical).

The chemical formula of this component is (C4H6O2)n. The last component is sodium borate (Borax). It is an important boron compound‚ a mineral‚ and a salt of boric acid. The chemical formula for sodium borate is (Na2B4O7·10H2O). In this experiment‚ both the sodium borate (Borax) and polyvinyl alcohol (PVA)
