relationship between mass‚ volume‚ and density of matter. 3. Use the particle theory to explain the differences between solids‚ liquids‚ and gases. 4. Comment on the accuracy of the statement below. Describe some exceptions to the statement if there are any. In general‚ solids are denser than liquids‚ and liquids are denser than gases. 5. Use the particle theory to explain why changing the temperature of a fluid can also change its density. 6. The density of a fluid usually decreases as the temperature

Hannah Herbert BioL121 9/16/14 Density and Making Solutions Objective and Background/ Theory of Experiment: The objective of the experiment was to determine the density of a metal along with the density of distilled water. In an attempt to help the experimenters more thoroughly understand the relationship between concentration and density. Archimedes a Greek mathematician in the third century B.C. originally determined the relationship between the amount of matter that is within a particular space

a sample. 18. Measure EACH side of the sample. 19. Multiply the values together. 20. Record the answer as the volume for the sample used. 21. To find the density of the data‚ divide the mass by the volume. 22. To discover the percent error subtract the accepted values ( which are given to the student by the instructor ) from the density. 23. Divide that number by the accepted value . 24. Multiply by one hundred. 25.That is the percent error. 26. Repeat these steps until all the information

Lab Report Question- Why do few objects float in water where as others sink? Hypothesis- I think the objects that have a greater density than water will sink. So whichever object has a density more than 1g/cm³ will sink in water. This is known as relative density where the density of the substance is compared to the density of water. Hence‚ the object that has a greater mass: volume ratio than water will sink. Materials- * 1 measuring cylinder * 1 rectangular prism * 1 ball of plasticine

buoyancy? – Buoyancy is the upward force caused by a fluid such as water. • What is Archimedes Principle? – The buoyant force is equal to the weight of the displaced water. • What is density? – Density is the mass of a material per unit volume. – Example: The density of steel is 10 times more than the density of wood. Hypothesis I think when the weight of the object is greater than the displaced water‚ it will sink. If the weight of the object is equal to the weight of the displaced water
