The olive ridley was named for the olive color of its heart-shaped shell‚ the carapace (U.S. Fisheries and Wildlife Service‚ 2012). As hatchlings emerge from their shell they are mostly black with greenish hues on their sides and about 4 cm in length. As they become adults‚ they develop their full olive green color and reach between 55 and

to find and examine the viscosities of ideal and non-ideal solutions. The ideal being the toluene/p-xylene and the non-ideal being the methanol/water. The second objective of this lab was to investigate the temperature dependence of viscosity (Halpern‚ 17-1). Introduction: Viscosity is the resistance to flow of a certain fluid. In this experiment two solutions are used. According to the definition of viscosity mobile liquids have a relatively low viscosity. Fluidity is the reciprocal
