ABSTRACT On the past two weeks‚ I have done an experiment on hydrostatics‚ or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

absorbed by the colorimeter. This could have affected the results because light could have reached the tubes causing some of the pigment to be damaged and not give accurate results. There are not many solutions for this but I suggest that we perform the lab experiment with sufficient time to do all of it in one day permitting more exact results on how much green light will be

Impurity Lab Report Aim: To find out the difference of the boiling point and melting point when adding impurity (salt) to water. Diagram: Method: 1.Set up the apparatus as shown in the diagram 2. Get a known amount of ice in the beaker (half full)‚ and a known amount of salt in another beaker 3. Measure the temperature (melting point) of the ice without adding any impurity (salt). 4. Measure the temperature (melting point) of the ice after adding the salt into the beaker. 5. Heat up

human evolution. Although no humans are being observed in this lab the concept of evolution is going to be looked up. The speciation is to see if by different modifications in the environment create a new species of finches. If no new species develop or the finches do not evolve to the changes in their surroundings will natural selection happen and will we no longer have finches on this island?

significant because the p value was lower than alpha. Therefore it is clear that the body temperature of an ectotherm could be affected by the elevation of the organism and convection. For future experiments in this subject it would be more beneficial to test microhabitats that vary more in temperature to truly be able to analyze the factors of thermoregulation in microhabitats. Introduction: The thermoregulation of ectotherms such as reptiles and insects has increased in “concern about the impacts

Electrostatics Lab Name: Bryan Michel Materials: Styrofoam cups Styrofoam plates PVC Pipe Fur Scotch Tape Procedures: You will be investigating charging object by friction. When you are asked to write your observations‚ please do so in a clear‚ complete manner. 1. Tape a piece of string to a Styrofoam cup and hang it from the edge of the desk so that it can move freely. Rub the outside of the cup with fur. Rub a PVC pipe with fur and bring it near the hanging cup.

The main purpose of this lab is to explain what emulsifiers and emulsions are and how emulsifiers affect emulsion stability. An emulsion is a mix of to or more liquids that usually do not mix together. One liquid is evenly dispersed in small droplets throughout the other liquid. Many emulsions contain water as one of the phases. There are two different types of emulsions. One type of emulsion contains oil droplets that are dispersed within water. It is considered oil in water emulsion. The other

The Results from the Gram positive tests indicated that the unknown #4 was Streptococcus pyogenes. All seven tests on the unknown matched S. pyogenes perfectly. The blood agar plate proved the unknown to be β hemolytic‚ meaning the unknown bacteria was capable of complete hemolysis. This test separated the unknown into the β Streptococcus group‚ narrowing the possible bacteria to S. aureus or S. pyogenes. The Catalase test was used to determine if the unknown could break down hydrogen peroxide
