Beach In A Beaker Introduction: The purpose of this lab is to create a heterogeneous mixture from substances commonly found at the beach. Sand and salt water will be added to the beaker to be separated. The sand will then be separated through the means of filtration. Then the salt will be separated from the water through evaporation. Theory: If the heterogeneous mixture is separated through filtration then the salt water and sand should be separated completely.A heterogeneous mixture is a mixture

an excellent method for preserving pharmaceuticals. The drying process of freeze drying consists of two steps‚ Primary Drying and Secondary Drying. The bulk of water removed from the product during freeze drying is via sublimation of all of the free ice crystals and organic solvents during the primary drying step which is a slow process conducted at cooler temperatures‚ safely below the product’s critical temperature. In secondary drying‚ the water molecules that are bound to the SLN were removed

supercritical state‚ allowing a phase transition from liquid to gas without the absence of shrinkage which causes a gel structure to collapse and fully dry. This process is known as supercritical drying process. Before they discover the process‚ it took days to create aerogels‚ but improvements have short the drying time to a few hours. The process still needs a high energy‚ leading to the high cost of aerogels. Aerogels also known as a space age material which is in one day it can be used in a many ways
