determine the best soft-boiled egg. In a soft-boiled egg‚ the egg yolk will be a thick liquid. Viscous (Viscosity) Viscous is having the property of viscosity (Dictionary-viscous). Viscous is a thick and sticky substance that is between liquid and solid. In egg‚ when an egg is soft-boiled‚ the yolk is a thick liquid. The yolk has the property of viscosity. In the question‚ consistency also means viscosity. Egg White There are four parts in an egg white. The innermost layer of the thick white is called

questions refer to Activity 2: Studying the Effect of Viscosity on Fluid Flow. 5. At what viscosity level was the fluid flow rate the highest? 1.0 6. Describe the relationship between flow rate and viscosity. The relationship is inversed; meaning a fluid that has a high viscosity has a slow flow because it resists the flow. Fluid that has a low viscosity will flow faster because it is less resistance to the flow. 7. Was the effect of viscosity greater or less than the effect of radius on fluid

Abstract The researchers are trying to figure out the effects of sedimentation‚ activated carbon‚ and decantation and boiling on purifying used coconut‚ palm and vegetable oil. The researcher’s experiment resulted to the change of appearance‚ odour and viscosity of each type of oil. The now purified cooking oil is faster to heat which makes cooking easier‚ faster and more efficient. The purified oil is quite beneficial however it does not take in as much taste as the unpurified ones. Overall the experiment

6. FIRST DERIVATIVE ZERO CROSSING METHOD 6.1. ABSTRACT: Simple‚ specific‚ accurate and precise 1st order derivative zero-crossing spectroscopic method was developed for simultaneous determination of PHENYLEPHRINE and EBASTINE from their binary mixture. In this 1st derivative zero-crossing spectroscopic method the amplitudes of the 1st order derivative of the spectra of the binary mixture containing PHE and EBS were measured at 252.2 nm (zero crossing of EBS) for determination of PHE and at 274.8

Distillation is a process in which compounds that are in the same solution become separated by their boiling points. For this to occur‚ a heterogeneous mixture has to be placed into a distiller‚ in this experiment a solution of 1:1 water and methanol was distilled. When distilling substances there are various methods of distillation that can be used. In this lab‚ simple and fractional distillation was used. The simple distiller is composed of a 100ml round bottom flask that is attached to: a
