Best Answer: There are two concerns with refreezing meat. The first is safety. If the meat has thawed in a refrigerator, then itâs okay to refreeze. In terms of other methods, make sure it doesnât sit in the âdanger zoneââ40Â°Fâ140Â°F (4Â°Câ60Â°C)âfor more than two hours.And if itâs been thawed by other methods, cook it before refreezing.est Answer: There are two concerns with refreezing meat.

Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent.This process differs from absorption, in which a fluid (the absorbate) permeates or is dissolved by a liquid or solid (the absorbent).Adsorption is a surface-based process while absorption involves the whole volume of the material.imilar to surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent, or metallic) of the constituent atoms of the material are filled by other atoms in the material.
The figure at right summarizes water reabsorption along the nephron. Water reabsorption is a passive process: water is reabsorbed by osmosis.In most of the nephron, water reabsorption is unregulated and coupled to solute reabsorption.The ability to excrete urine that is more concentrated than the extracellular fluid (ECF) depends on the creation of a hyperosmotic environment in the medulla.As the collecting duct descends through the medulla, the increasing osmolarity in the interstitial fluid drives water reabsorption.he ability to excrete urine that is more concentrated than the extracellular fluid (ECF) depends on the creation of a hyperosmotic environment in the medulla.
