Energy density

Hypothesis The objective of the density determination lab is to determine/compare the average density of pre-1982 and post-1982 pennies. This can be achieved by finding the mass to volume ratio then averaging the results. The purpose of this lab is to find out if the difference in composition of the pre and post pennies will affect their densities. Pennies made before 1982 where majority copper but pennies minted after 1982 are made with mostly zinc. With this background knowledge, we expect the

Most to all experiments and labs require some form of measurements. Because there are many various kinds of measurements, it is important to be aware of the different factors of each measurement involved

Density: Using Experimental Techniques to Solve an Inquiry based problem ABSTRACT The topic of this experiment is Density. The objective is to find two ways in which the density of a given object can be determined, and to find out which of the two ways is more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object, and they were chosen since

to combine units to determine density and concentration, and to use laboratory equipment to create serial dilutions and determine the density and concentration of each dilution. Procedure: Measure the volume, mass, length and temperature of a variety of items. Create dilution of sugar water. Data Tables and Observation: Fill out the data sheet (below) for the experiment and submit with this form. Recording data carefully

effect is the phenomenon that occurs when floating objects that don't normally float attract one another. At the root of the Cheerio Effect are basic physics concepts such as buoyancy, surface tension, gravity, and the meniscus effect. Buoyancy or density of an object compared to the liquid or air surrounding it, determines whether an object submerged in water or surrounded by air will sink, float, or stay put. Buoyancy is what keeps objects afloat. If an object is less dense than the liquid or air

Density: the compactness of a substance. That is the first thing that came to mind when I saw that diet coke floated in water and the cherry coke that sank in water. My group members and I measured the density of all three substances (diet coke, cherry coke, and water) and collected the data to see if density really was the cause. Based on our results, it turns out density really is the reasons diet floats and cherry sinks. After we collected our data from the lab, we did many calculations and found

The purpose of this experiment is to learn how to measure mass and volume and to determine the density of water, alcohol, and a solid. We will be using a laboratory scale or balance and the graduated cylinder to determine the density of water and of alcohol. First, place an empty graduated cylinder on a balance, determine its mass and record the value under the Density of Water: Data Table. Next, pour 25 mL of tap water into the graduated cylinder. Place the cylinder on the lab bench and read the

Density is the degree of consistency measured by the quantity of mass divided by the volume. Buoyancy means the ability for an object to float in water. When talking about density we are trying to figure out how depth the object is in the water or how much water do we need in order for the object be closely deeper to the water. For instance, if we place a ball in the water and it has a mass of 4grams and the water has a volume of 2, the density of the ball placed in the water will be 2 grams per
