Energy density

Have you ever wondered why your cereal clusters together after milk is poured or why it sticks to the side of your bowl? Even if you try to pull them apart, they come together again. This is a spectacle that happens every day but we just don’t really notice it. Most people don’t really realize that it’s happening everyday. Using fluid mechanics, we can determine why floating objects come together due to surface tension, viscosity and buoyancy (Grayson, 2014). This cheerios effect also applies to

Questions will be out of order. How does measurements of SI help with business and commerce? Companies need the exact amount and ingredients of what to put in their product. Such as a can of soda. A can of soda normally contains 12 fluid ounces. 12 fluid ounces is approximately 354 grams. These companies are using some sort of measurement system. We use something called "imperial system" where as most countries use metric system. Governments don't want confusion to be amongst them, so they only adopt

In order to investigate factors influencing the flow of granular materials such as sand and pea gravel, researchers used the funnel apparatus shown below. Very small ceramic beads were placed in the top funnel. The top funnel was then sealed. The beads passed through the apparatus and fell into a container on top of a digital balance. A computer recorded the mass of the collected ceramic beads over a period of time. Funnel apparatus drawing Ceramic beads with diameters from 0.15 to 1.00 millimeter

5861 Are these Objects Made of the Same Material? Every substance has its own unique density due to all of the atoms mass, size, and arrangement being different for each atom. Density is the relationship between two characteristics of matter which are mass and the occupied space. Density is a characteristic property, meaning the density of a substance will stay the same. In an investigation the objects densities would be calculated to determine whether the objects are made of the same material. The

Aptanta 9B Mr. Anthony Science- Physics The difference in density between salt water and tap water I. Problem: • Will an egg float on fresh water or tap water? II. Background Information: Density is a measurement of how matter is in a certain volume/object. It is basically the compactness of an object. If the molecules are closer to each other, therefore it’s denser. If you compare a cuboid Styrofoam and a cuboid metal, the metal would weigh heavier because it is denser. The denser the object,

accepted. The data collected during the experiment accepted the hypothesis was that the sand from film canister #1 had a density of 0.32 g/mL3 and the canister would float on top of the water. The sand from film canister #2 had a density of 0.99 g/mL3 and the top of the canister would be right below the surface if the water. Finally, the sand from film canister #3 had a density of 1.17 g/mL3 and the canister sunk to the bottom of the container of water. Based upon the data collected from the lab,

Discussion: Define and explain density in your own words. Density is calculated by dividing its mass by its volume (D=M/V). Density also describes how compact a substance is (amount of space occupied within a certain area). What is the difference between mass and density. The differences between mass and density are that mass is the amount of matter in an object and density is a measurement of how close the molecules are packed tightly together in a certain amount of space. In this lab, can

through the use of a diverse set of glassware: graduated cylinder, volumetric pipette, and burette. These unique measuring instruments played a role in concluding the densities of the two soft drinks, Coke and Diet Coke, and whether or not a statistical difference existed between the two substances. Conversely, the resulting densities determined by each of the differing glassware were assessed and compared to each other in terms of accuracy and precision, with the most precise tool that produced consistent

In class we did a lab that helped displayed density. Density is the degree of compactness in a substance. To calculate a specific amount of density you will need to divide the mass by the volume and your quotient should be the density. In our investigation we were told to manipulate the density of the water using different amounts of salt to make an egg float, sink , and levitate, using various amount of trials. The materials we were given for this investigation was water, a beaker, and an egg
