take the mean of the two temperatures you have measured as the effective temperature of the water during the calibration. Calculations 1. Find the mean of the four trials. The mean volume can now be determined from the mean mass and the density of water at the temperature you determined in 6 above. However‚ there is a correction to be made for the upthrust of air on the water during the weighing. In normal day-to-day use of balances we neglect this correction‚ but now that we are interested

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‚

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

water‚ at this point the water is dense enough for the egg to float. To find the density of salt water first measured the mass of salt water after adding salt into 800ml of water. The following results are the density of salt water every time increasing 1 table spoon of salt into 800ml fresh water. One table spoon of salt is also equal to 10g.

Cartesian Diver Essay The Cartesian Diver is named after the French scientist Rene Descartes. This experiment is supposed to show buoyancy‚ density and different forms of matter at work‚ when demonstrated. To create the Cartesian Diver‚ you’ll simply need: • A empty plastic bottle • A plastic eye dropper • Water 1. Fill the bottle with water‚ but be cautious of spills. 2. Very carefully‚ drop the dropper inside the bottle. Then‚ seal the cap on very tightly. 3. Squeeze the bottle‚ but not too
