In this experiment we used a scale to find mass and a graduated cylinder to find the volume of the substances, water, rubber stopper, Pepsi and diet Pepsi. Then we used the formula density= mass/volume to find each substances density. This lab shows the use of the density formula and helped improve measuring skills. ... Next we poured 50 ml of tap water into the 100ml-graduated cylinder, read and recorded the volume. ... Data Results Density of water Mass of graduated cylinder 42.03 g Mass of cylinder and water 140.93 g Mass of water 98.9 g Volume of water 100 ml Density of water ...

Solids are weighed to determine its mass then put in water to measure the volume. ... Record the volume of the stopper. 7. Now by using the density formula D=m/v you will get the density. ... Of water in the cylinder. 3. ... Now that you have the mass and the volume use the density formula D=m/v and that will give you the density. 6. ...

Plug the radius in this formula, 4/3x x r , this will give you the volume of the sphere. ... Plug the radius in this formula 4/3x x r , this will give you the volume of the sphere. ... Now take the large cylinder and put it under the tube as you drop the lead weight into the cup. This will cause some water to be displaced, the displaced water will go out of the tube and into the large cylinder. Now measure the amount of water that is in the cylinder which is the volume. ...

Cable Department of Mathematics, Allegheny College, Meadville, PA 16335 The American Mathematical Monthly, February 1984, Volume 91, Number 2, p. 139. In most calculus books there is little effort given to showing that the cylindrical shell method and disk method give the same value when computing the volume of a solid of revolution. ... In this paper we shall show that the cylindrical shell and disk methods give the same value if the region revolved about the y-axis is bounded by and the x-axis, provided is a differentiable function on and is one-to-one. The proof is simple and uses t...

Last of all we filled the flask with water to the bottom of the stopper, and measured the volume of the water by transferring it into a graduated cylinder. The water represents the original amount of the air that was contained in the flask and now represents the newly collected CO2 Data Table Mass of flask and stopper assembly, filled with air 146.034 g Mass of flask and stopper assembly, filled with carbon dioxide 146.195 g Temperature of the air 24.8 C Temperature of the CO2 26.3 C Barometer Reading 751.5 mm Volume of the flask 253 ml Volume of t...

Gunpowder that is used in modern ammunition is placed inside a cylinder that is sealed with a head. ... The explosion inside the cylinder of a bullet is caused by a spark of heat created by the firing pin when it strikes the small flint in the bullet. ... There are many different chemical formulas for gunpowder. The chemical formula of early gunpowder consisted of a mixture of potassium nitrate (saltpeter), charcoal and sulfur. ... An explosion is a phenomenon due to the sudden enlargement of the volume of a body. ...

It was also used by Zu Chongzhi in the 5th century AD, who used it to find the volume of a sphere. ... Around AD 1000, the Islamic mathematician Ibn al-Haytham (Alhazen) was the first to derive the formula for the sum of the fourth powers, and using mathematical induction, he developed a method that is readily generalizable to finding the formula for the sum of any integral powers, which was fundamental to the development of integral calculus. ...
