Density is determined using the formula d=mass/volume 2 how does density affect the floating and sinking in water for an object to float, relative to its surroundings, it must be less dense than its surroundings 3 how can the physical property of density be used to identify an unknown substance each substance has. Experiment measurement: length, mass, volume, density, and time 2 pencils or pens 1 chair or step stool 5 circular objects of different size (cups, plates, etc) 1 computer and spreadsheet program 1 1 lab partner cup filled with tap water the densities of solids are usually reported in grams per cubic. Density is mass per volume lead is dense, styrofoam is not the metric system was designed so that water will have a density of one gram per cubic centimeter or 1000 kilograms per cubic meter lead is about 10 times as dense as water and styrofoam is about one tenth as dense as water ii purpose of the activity. To determine the density of solid that is denser than water, using a spring balance and a measuring cylinder a) as performed in a real lab: take a graduated glass cylinder of proper size and mean gravitational mass of the solid block, =gwt (by spring balance) 2 table: for volume of the solid block (v).
Liquids and regularly shaped solids by direct measurement of mass and volume solids by indirect volume measurement liquids and irregularly shaped solids ( eg density using archimedes principle 1 suspend the cylindrical metal sample in the liquid as in part iii and measure its apparent mass when submerged 2. Exp 2 laboratory techniques and measurements purpose: this lab experiment involves being able to measure different si units of measurement mass, volume, length, density of liquids and solids, time, temperature, moles, and molecular weight then we converted between si units, performed a dilatational series, and. To calculate density of an object, you need to know the mass and volume of the object these problems show how to calculate density of a solid and liquid.
Introduction when given an unknown substance, there are only a few ways to determine what it is one way is to measure its density at a given temperature any pure substance has a specific density at a specific temperature density is defined as being equal to an object's mass divided by its volume. Lab iii mass, volume and density of a solid problem: what is the relationship between mass and volume of different geometric solids made of the same 1) define density give an example showing how to find the density of an object 2) describe 3 ways you could find the volume of a small sphere 3) a cube has. Volume) of a material (solids, liquids, gases) goals 1 understand that density is a property of matter 2 calculate the density of regular and irregular objects and volume and mass 1db predict the effect of a temperature change on the properties (ie, pressure, density, volume) of a material (solids, liquids, gases) 1. In my class this lab comes on the heels of our lab on measuring the density of solids and liquids to pique students ideas, i show them an empty balloon and a filled balloon and ask them to tell me how we can measure the properties of the gas inside the balloon (mass, volume, density) piece of aluminum foil (2 x 2.
The same mass, but more volume – means lower average density the crown was less dense than pure gold, so it had to be stretched with another metal this experiment helped archimedes discover the relation of mass to volume and it leads to some of the main questions we need answers for in working. Mass of cylinder + 5 ml of water + solid 4 new volume of water (lower meniscus of water) 5 mass of solid (line 3 - line 2) 6 volume of solid (line 4 - 5 ml) 7 density of solid( line 5 divided by line 6) 1 can you identify the solids used in this experiment 2 calculate the density (g/ml) of mercury if 975l weighs.
Expansion coefficient of solid and liquid materials and the thermal expansion coefficient measurements were made on a pure nickel sample to test the 2 where m is the sample mass, v is the sample volume, and t is the sample temperature the validity of this density measurement technique uti- lizing htesl was. Overview source: laboratory of dr michael evans — georgia institute of technology the ratio of the mass of a substance to its volume is known as the mass density or, simply, the density of the substance density is expressed in units of mass per volume, such as g/ml or kg/m3 because the density of a substance does. From sep supplemental kit - matter – one container of sand and one container of gravel for each pair or triad of students, containers of other particulate solids for extension activities (cornmeal, salt, flour, etc), funnels foss energy and matter activity 3 – parts 2 and 3 (measuring mass and volume using the metric system.
Page 2 of 5 in part b of this lab, the density of aluminum will be determined using aluminum pellets again, mass will be measured using an electronic balance, in grams (g) however, since the pellets have irregular shapes, their volume must be measured indirectly using the technique of water displacement (also known as. This experiment consists of three parts: measuring the density of an irregularly shaped solid, measuring the density of a unknown liquid sample, and making multiple measurements of the this leads to some careful consideration of significant figures when calculating the density of the object (mass divided by volume.
Materials for experiments 1 & 2 3 150 ml beakers (or pour 150 ml of water into beaker #1, 150 ml of corn syrup into beaker #2, and 150 ml of vegetable oil into beaker #3 (if you are using if you want to find out the approximate density of each, you can calculate it using this formula: density = mass/volume on earth we. Directions for the comparing mass, volume and density lab. In this lab the density for regularly-shaped, irregularly-shaped objects and ionized and deionized water will be calculated by measuring both volume and mass for the density of the regularly-shaped object 1 obtain one of the solid blocks that were provided in the lab and record its code number onto our data sheets 2. Density the density (ρ) is elementary physical property of matter for a homogeneous object it is defined as the ratio of its mass (m) to its volume (v) – eq1 v m = 2 2 ρ ρ =  b density determination of solid matter by pycnometer pycnometer can be also used to determine the density of homogeneous solid object that.
