pressure and temperature outside. [1] As the pressure on the object increases the volume of the object decreases and hence the density of the object increases. [1] On the other hand‚ as the temperature increases the volume of the substance increases and its density decreases. [1] The density of a substance can be found if the mass and volume of that substance are known‚ since the density is the ratio of the mass to its volume Density = The SI derived unit for the density is kg/m3.

slope for water and alcohol and apply the understanding to determine the volume of a quartz sample without measuring the volume or calculating it. Hypothesis: The hypothesis of this lab was by using the density of alcohol we could calculate the density of a quartz samples. Controls and Variables: Independent variable: Volume of water and alcohol Dependent variable: The weight of the liquid or solid Controls: The volume of the water should be the same each trial Materials: Triple Beam Balance

access the Server DC but I still do not see any install folder. 5. How much available shrink space is contained in the volume? 449MB 6. How is the last volume you created different from the previous ones? Explain why. The size of the volume is different. By shrinking the file it made the volumes less than 2000MB 7. What do you suppose would happen if you created another simple volume out of the free space left on the disk? I think that the it will run out of recourse. 8. Were you successful? No

Finding Density Density is defined as mass per unit volume‚ which can be used to determine the object or substance observed. Many people use the density of objects to find what it is and how to classify the object. The object of the lab conducted was to find the density of the substances given and to find what the unknown liquid and solid were. The process to finding what the unknown solid and liquid were‚ was to find the density and to conduct multiple trials so when the density

instrumental error that might be present in an instrument. • Investigating the limits and capabilities of a measuring instrument. • Determining the accuracy of the actual volume of a volumetric pipette‚ volumetric flask & measuring cylinder. INTRODUCTION The purpose of this experiment is to investigate the measurement of the actual volume contents of volumetric glassware. If there is a slight variation in this instrument‚ it would cause systematic error and thus‚ the accuracy of results of an experiment

purpose of this experiment was to determine the density of an object by measuring its mass and volume. Hypothesis When the rubber stopper is dropped into the overflow can‚ the volume displaced (mL) will be equal to the number of grams of the rubber stopper. I think this will be the outcome because I learned before that 1g=1ml‚ so for every gram dropped into the overflow can‚ 1 ml should be displaced (the volume). Therefore I think the density of each rubber stopper would be 1g/ml. Materials - 5 different

precisely‚ the volumetric mass density‚ of a substance is its mass per unit volume. The symbol most often used for density is ρ. The unit of density is kg/m ². Here is the formulae of density: Density = Mass (kg) Volume (m ³) Hypothesis: According to PubChem from the internet‚ it states that the density of water is 999.97 kg/m³ .

mass of the object by the volume. The average density of an object can determine if it’ll sink or float when submerged in liquid. The average density for water is 1.0g/ml. and if an object with the average density greater than 1.0g/ml‚ then it’ll sink. Vice versa‚ if the density is less than 1.0g/ml‚ it’ll float. For this particular experiment‚ when the bottle is squeezed‚ the air inside the diver is compacted‚ and the volume decreases. When there is a change in volume‚ there is also a change in
