Volume

lab was to determine the effect of temperature on the volume of gas when the pressure is consistent and to verify Charles’ Law. The data from the experiment reveals that as temperature increases, so does volume. This also indicates that as temperature decreases, the volume decreases as well. Procedure 1) Select a 60 mL Syringe Sealed from the Gas Syringe item under the Equipment menu. Set the volume to 20 mL in the Initial Gas Syringe Volume dialogue box. 2) Click on the syringe and select Thermometer

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 the density of an object may be found using its mass and its volume. The experiment yielded two different density values, however when error analysis was conducted, the water displacement method was proven to be more accurate. INTRODUCTION

16, 2015 CHM 23000-23   Introduction Matter is described as any object that holds mass and volume. Mass is the amount of matter in an object that is usually explained in the unit of kilograms. Volume is defined as the amount of space that matter takes up usually described by the unit liters. While mass and volume relate to matter, it also relates to density. Density is the amount of mass per unit volume. Common units for density include grams per milliliter for liquids, grams per centimeter for

Volume Measurements: The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water

Objective Objectives will be calculating densities of regular solids, determine the densities of solutions by plotting mass versus volume. Predict whether objects will sink or float in different solutions based on the densities of the solutions and objects.

greater volume and no increase in mass leads to a lower density. The mass is 132g The density of the “silver” that is in question is 6.4 g/cm3 however, the density of pure silver is 10.5 g/cm3 Error Analysis: Error in the experiment could

II. Introduction a. The purpose of this density lab was to show the different ways density can be measured. Density is the measure of mass in matter. To find density, you would have to find the mass and the volume of the object. Then the mass would have to be divided by the volume to find the density. Density and specific gravity are similar because specific gravity is the density of a substance in comparison to the density of the standard. In this case, the standard is the density of water. The

It used mass, temperature, length, volume, density, and making a dilute solution. I learned the importance as well as the difficulty of making proper measurements in a lab setting. If one measurement is off, it will throw the entire equation off. This will give either incorrect or inaccurate

shape on the ratio of surface area to volume. Complete the following exercises. Part 1 Let’s investigate how size influences surface are to volume ratios. Let’s assume we have a cube with a volume of 1cm3. Each side of the block equals 1cm. Picture a die for each cube. 1. How many sides does a cube have? 2. Let’s use 1 block to represent a small cubed organism and 8 blocks to construct a large cubed organism. Complete the following table. Total Volume Total surface area Surface area:volume

mass and volume from the small pieces of clay from all three trials and I find the average which is 14.7g (mass) and 8.7cm3 (volume). Then I divide using thee formula d=m/v and for density I got 1.7g/cm3, rounded to the nearest tenth. Next I did the same for medium of all three trials in which I got 22.5g for the average of the mass and 13.3cm3 for the volume. I divide using the same formula and also got 1.7g/cm3, rounded to the nearest tenth. Lastly I find the average of mass and volume for large
