all there were seven samples‚ namely water‚ isopropyl alcohol‚ coconut oil‚ wooden block‚ marble‚ pebbles‚ and an unknown liquid sample. For the density of water‚ a clean and dry 100ml graduated cylinder was weighed and 50ml of water was added into the graduated cylinder. The graduated cylinder with water was weighed again to get its mass. For the density of a liquid other than water‚ a clean and dry 10ml graduated cylinder was weighed and 5.0ml of the different liquid samples (isopropyl alcohol‚

volumetric glassware should be calibrated to measure the volume that is actually contained in or delivered by a particular piece of glassware. The calibration is done by measuring the mass of water contained in or delivered by the glassware. The density of water at a particular temperature is used to convert mass into volume. Pipettes and burettes are calibrated to deliver specific volumes whereas‚ volumetric flasks are calibrated to contain basis. MATERIAL AND PROCEDURE The materials used

Locomotion in an animal with an endoskeleton (fish) * Water has a higher relative density (800 times higher than air) and is a viscous medium to move through. * The body of a fish is of a streamlined shape to move quickly in water. * The streamlined shape of a fish: * a) is long ellipse tapering to a point (shaped like a torpedo) in the direction of the flow of water. * b) reduces the drag (a drag is water resistance caused by friction between moving water and the

obtaining an average density & boiling point for my liquid and comparing them with the known densities & boiling points of liquids in the CRC handbook of Chemistry & Physics. I will perform these experiments using three different measuring tools (graduated cylinder‚ burette & pipette) to evaluate the precision of each one. Results: Density 1‚ 2 & 3 calculated by using graduated cylinder to obtain volume. Density 4‚ 5 & 6 calculated by using volumetric pipette to obtain volume. Density 7‚ 8 & 9 calculated

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
