objects with different amount of density and put them each in ten cups of water. I then put in teaspoons of water and recorded whether or not the objects floated until all the objects were floating. I was able to see how an objects density affects how much salt is needed to make it float. Page 2 Introduction/ Research When trying to make an object float it depends on its density. Density is the “mass per unit volume.”[7] An object floats if it has less density then water. Objects like a boat

retaining walls‚ earth dams‚ and airport‚ require man-placed soils‚ or fills. These soils are loose (weak) and must be compacted to increase their strength characteristics. • Soil compaction is defined as the method of mechanically increasing the density of soil by reducing volume of air. 2 General Principles • The densification is accomplished by pressing the soil particles together into a close state of contact with air being expelled from the soil mass in the process‚ thereby increasing

description of the lab and it importance. Answer three questions a. What did you do? In this experiment we were exposed to a variety of important concepts related to quantitative experimentation‚ including the proper use of glassware‚ and analytical balances. b. How did you do it? Briefly describe the procedures in 1 sentence. We calibrate a volumetric pipet and flask. We also calibrated a beaker and 50 mL buret. We also calculate the difference between the expected density and density obtained by

non-scattering‚ absorbing medium‚ the intensity of the light after passing though the medium is given by: (1) Where I(0) is the intensity at s=0‚ a is the absorption cross section of a single particle for radiation of wavelength ‚ n is the number density of the medium‚ and s is the length of the medium. We can apply the relationship to solar radiation passing though the atmosphere. From equation 1‚ we find that ‚ the transmissivity of the slant path of the atmosphere at a given wavelength is

tower is at achieving equilibrium multiple times which results in greater efficiency. The same goes for decreasing plate height. In design‚ there are tables and assumptions which ease the process of finding the tower height and area. In this particular lab‚ we have a tower and are testing multiple cooling loads and air flow rates for a constant water flow rate. By measuring the difference between the inlet and outlet wet and dry bulb temperatures‚ we can approximate Noy using the following equation:

Title: Archimedes principle Objective: To use Archimedes Principle to determine the density of an object more dense than water. Introduction: Archimedes ’ principle is a law of physics stating that the upward force (buoyancy) exerted on a body immersed in a fluid is equal to the weight of the amount of fluid the body displaces. In other words‚ an immersed object is buoyed up by a force equal to the weight of the fluid it actually displaces. Hence‚ the buoyant force on a submerged object is the
