Part I: Density of Unknown Liquid Calculate the mass of the liquid for each trial. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) Trial 1: Empty graduated cylinder is 25.5 subtracted from 36.5 of the liquid and the cylinder combined equals 11 grams of liquid. Trial 2: 36 grams of water and liquid combined minus the 25.5 of the empty cylinder means equals 10.5 grams of liquid only. Trial 3: Again 36 grams of liquid and the empty cylinder

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

Look in the yellow data box in the top left corner of the window. Record the mass (m)‚ volume (V)‚ and density (ρ) of the wood block. 5. In the middle of the screen there is a container of water. Record the volume of the water. 6. Drop the wood block into the water. Does the wood block float? Explain why or why not. 7. Place the block so that

Also‚ pulsars are highly regular astronomical clocks. Density varies with temperature and pressure. It would be necessary to measure both mass and volume very accurately in order to use the density of water as a standard. People have

Title: Laboratory Techniques and Measurements Purpose: To properly use‚ understand‚ and correctly convert the scientific measurements such as: finding density‚ converting centimeters to millimeters‚ 3 different units of temperature‚ etc… Procedure: I used a metric ruler to measure the length of the objects‚ a thermometer to determine the degrees of the water‚ and a scale to determine the mass of the designated objects. I used the proper equipment to measure out or hold the item. After I gathered

dropper’s density. When the density of the dropper increased‚ it became more dense than the water it was in‚ causing the dropper to sink. When pressure was released‚ the air was sucked back into the dropper making it less dense than the water again‚ so it floats back up to the top of the bottle.
