Experiment 1.3 How Dense Is It

Experiment 2 “Density” was about how to measure the mass and volume and determine the density of water, alcohol, and a solid. For this lab, we begin by calculating the mass of empty graduated cylinder and the mass of 25 mL of tap water. After taking the mass of water and cylinder, we record it on “Density of Water: Data Table”. Since we did not have enough time of complete the whole lab, so we skipped the procedure to measure the density of alcohol. We jumped to the next procedure, which was density of a solid. For that we used a copper and it density 8.95. For this lab, my partner and I did not make any mistakes or errors. But, for better improvement I think we should have more time to complete the whole lab. I felt like we was rushing through

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.

In the final experiment, Density of the Mass Set, the experimenters used the vernier caliper to lead them to the volume of some of the figures in the mass set, and this eventually led them to find the density.

The purpose of this experiment is to learn how use a variety of tools that will aid in the gathering of data. This data is then used to calculate different measurements including, volume and density. The experiment will also further understanding of measurement errors using the data collected.

In this lab, the density of 20 glass beads were determined using two different methods and the results were compared to see how close the values were to each other. In first method the volume of each individual bead was measured using the diameter of each bead, along with the mass. In the second method the beads we treated as a whole unit. The total mass was measured and volume was measured based on the amount of water that was displaced in a graduated cylinder. Then, the beads were swapped with 20 different glass beads of the same type. The procedure was repeated and the results were compared to the data of the first bead set to look for any systematic errors that may have occurred. During the experiment, the data was

The type of measurement that I was able to record with the most number of significant figures was the mass. To measure this, I used an electric scale which showed up the the 0.001 place, and when objects were placed on it, it showed at least 4 significant figures. The exactness of these measurements mean that they were precise.

Collect the materials from designated spots. The rocks chosen for the experiment should have a number written on them. Be sure to list the number of each rock on the lab sheet. 2. Label a spot on the lab sheet for each partner in the group for both trials.

In this lab experiment, we determined the densities of two solid substances that have regular and irregular shapes by water displacement and dimension methods. For the regular solid substance, the value of density was 0.18g/mL, while for the irregular solid substance, the density was 0.22g/mL. Primarily, we wanted to understand the significance and the meaning of the density of a substance. We discovered that density does not vary on the size and the amount of the substance. Instead, it depends on the composition of the substance. Therefore, it is an intensive property. In order to find density of substances, we calculate the mass of these substances, and we divided them by their amount of values. The basic units for the measurement of density

For this lab a series of different liquids can be used , have at least 3 different liquids, and have a graduated cylinder. In this lab you can pour each liquid into the graduated cylinder one at a time and then once all of them are poured absorb to see which ones are at the top of the cylinder and which are at the bottom. Using observation and knowledge about density those participating can figure out which what type of liquid each is. Another extension to the lab could be to have all of the objects be measured using water displacement and the method to use dry volume. Each object would be measured for it’s wet and dry volume then those measurements would be used to find the density of the objects. Finally the densities found with wet volume and dry volume could be compared to the actual density of the material to show which method came up with a more accurate outcome. One last extension for this lab could be use different objects but instead of trying to find the density try to find the volume or mass. The density of each material would be given and then from there those participating would use the density to volume/ mass formula to determine what the mass or volume then use the gathered information to make the density with the material. This experiment would help to further practice and understand the process of calculating

The overall objective of this lab experiment is to learn about measurements. 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 with the current lab experiment. It is also important to have a general understanding of them because they will need to be used in calculations for the lab. Precision and accuracy will be used most in this lab. A knowledge of the following

The objective of this lab experiment was to determine the density of a set of plastic beads by using two different methods and decide which method was better. Density is a physical property that is defined as the ratio of an object’s mass to an object’s volume. Also density can be described as the measurement of how compact a substance is in a given space. To find an object’s density, it is necessary to measure the object’s mass, the amount of matter present, and volume, the space it takes up. Also when studying density, it is important to note how objects with varying densities behave. The density of water, at room temperature, is 1.00 g/mL and is often used to help determine the density of a substance based on if it sinks or floats in water. The measurement of the object’s density is important to the plastic company because it allows the company to make sure the product meets the design specifications. In determining the object’s density, the methods of displacement and floatation, were implemented.

Within this experiment all units implemented were converted to SI units and all data was recorded to four significant digits. Therefore, all distances were measured in metres, time in seconds and weight in kilograms.

In the first part of the experiment, the fundamental quantities-length, mass and time were estimated simply by guessing. Even though it can be helpful sometimes to test a hypothesis, huge percentage errors in the measurements showed that human errors can be significant and therefore, we need more sophisticated techniques for more accurate measurement. For instance, using Vernier calipers is more precise than guessing the length or more accurate than the ruler.

The purpose of this experiment was to measure the density of a solid and a liquid using Archimedes principle. Archimedes is one of the greatest inventors and mathematicians of all time. The principle we used in this experiment was discovered when Archimedes stepped into a full bath tub. Using Archimedes principle, we were able to determine the density of a lead rod, water, and an unknown liquid.
