Lab.5 : FLUIDS Name: ------------------------------------- Student ID: ------------------------------- ORIGINAL DATA AND OBSERVATIONS Pressure and depth Compare and contrast the water flow from the various holes in the cup At which level is water pressure the greatest? (Explain) State the relationship between depth of water and pressure exerted by the water at that depth. Atmospheric pressure What happened to the can? Explain why this occurred (include the reason it was necessary to boil the water in the can) Suppose that, instead of boiling water in the can, you had simply taken an empty can, heated it on the hot plate, and flipped it over in the ice water. Would the same effect have occurred? Explain why or why not? Archimedes principle THE OBJECT FLUID Sinking or Floating ? Mass (kg) Volume (L) Density (kg/L) Density (kg/L) Volume before (L) Volume After (L) Change of Volume/V (L) Mass of V (kg) 3.00 8.00 1.00 100.00 7.00 8.00 1.00 100.00 7.80 8.00 1.00 100.00 7.00 6.00 1.00 100.00 7.00 4.00 1.00 100.00 Table 1. For all the objects that are floating, How does the mass of the water displaced compare to the mass of the object.
