empty graduated cylinder with the mass of the cylinder and liquid. For the density of solids‚ the rectangular block was weighed and the volume was determined by measuring the length‚ width and thickness. For spherical solid‚ the circumference or diameter was measured and using the specific formulas‚ their volume was determined. For irregular solids‚ the volume was determined by water displacement method using a graduated cylinder. ( Write your results here. For example) It was noted that the

decolourisation of DCPIP from blue to clear as the indicator. • You first need to estimate the volume of a known concentration of vitamin C solution required to decolourise 2 cm3 of DCPIP solution. • Then you need to determine the volume of fruit juice that decolourises 2 cm3 of DCPIP solution. This gives an estimate of the concentration of vitamin C in fruit juice. • This value is then multiplied by the volume of the fruit to obtain its total vitamin C content. Apparatus: 50 cm3 beaker 100

To learn how to calculate density and concentration of dilutions. Procedure: I used a ruler‚ thermometer‚ and scale to take measurements. I used a graduated cylinder‚ short step pipet‚ scale‚ and ruler to determine volume and density. I used a volumetric flask‚ graduated pipet‚ pipet bulb‚ scale‚ and glass beaker to determine

absolute pressure and volume of a given mass of confined gas are inversely proportional‚ if the temperature remains unchanged within a closed system. 2. An outline of what this project is about. In this project I will be testing to see if pressure and volume are inversely proportional to one another. I will use Boyle’s apparatus and a pump to test this. When the pump is pumped it will raise the pressure in the tube. The oil level will then rise therefore decreasing the volume of air in the tube

different methods have been recorded by various sources backed up by science. I have found three that I will test in order to find which produces the fluffiest‚ or least dense‚ batch of cupcakes. They allow for a greater leavening‚ or increase of volume of baking dough caused by the formation of gas bubbles. The methods to create this effect on the cupcakes are using egg whites only‚ mixing each ingredient separately before adding them to the mixture‚ and adding a teaspoon of corn starch to the mix

favorite subject in math. I have always struggled with geometry‚ especially with memorizing formulas to solve problems such as finding volume‚ surface area and more. I always found formulas to be such a bother and even after learning one and mastering it somewhat‚ I usually ended up forgetting the formula. Fortunately‚ the formulas that I had the most trouble with‚ being volume‚ surface area‚ and area‚ have finally began to stick with me. Fifth grade really lowered my enthusiasm and sparked a small hatred

SCIENCE: MASS‚ VOLUME‚ AND DENSITY Purpose: The purpose of this experiment is find the density of two metals using their mass and volume. Introduction: The purpose of the experiment that was conducted was to measure and calculate the density of two different metals. Density is an important characteristic of a material. The density of an object shows how much mass is contained in the unit volume. To calculate the density of metals the experimenters had to find out the mass and volume of each and

measurements. So our first thought is that we needed to find out the volume of the classroom with the indents and the volume of a 12 inch softball. Within the measurements of the walls and the indents we immediately wanted to subtract the indents within the walls because it was easier and we did not have much math to do. A factor that could be involved is that there are different sizes of softballs so it would be a variety of different volumes because of the size. Another factor would have been the wrong
