Premium Density Experiment Science
Density is how compact particles are inside an object. Objects can be different sizes but have the same density because the density depends on how close particles are together‚ not the size of an object. The density of water is 1 g/㎤. Any object with a density less than that will float. Any object with density more than that will sink. Carbon dioxide‚ or CO2‚ also played a big role in this experiment. Many soft drinks contain CO2. Studies show that Sierra Mist had the most carbonation out of

The Lab Report Assistant is simply a summary of the experiment’s questions‚ diagrams if needed‚ and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing

DENSITY DETERMINATION An old riddle asks “Which is heavier‚ a pound of feathers or a pound of lead?” The answer is obvious‚ of course‚ since a pound of feathers and a pound of lead both weigh the same‚ one pound. However‚ there is clearly something different about a small piece of lead and a large bag of feathers‚ even though they weigh the same. What is this difference? The relationship between the lead and feathers is expressed by the physical property called density. Density is defined

Chemistry 11 Santa Monica College Determination of Molecular Mass via the Dumas Method Objectives: • To determine the molecular mass of an unknown volatile liquid using the Dumas method and the ideal gas law. Background: In the early 19th century‚ Jean-Baptiste Dumas‚ a distinguished French chemist‚ created a relatively simple method for determining the molecular mass of a volatile substance. In this experiment we will use a modified version of his technique to determine the molecular

ordinary laboratory pipette may be expected to deliver its nominal volume with good precision and good accuracy if it is used in the way recommended. In this experiment we investigate the precision and accuracy of such a pipette by making accurate determinations of the mass of water it delivers in repeated operations.

Classification of Settleable Solids There are different factors to be consider in choosing the type of sedimentation to be used‚ some of it are particle size‚ viscosity‚ solid and solution densities as well as the characteristics of the particles within the slurry. In this figure‚ it illustrates the relationship between solid concentration‚ interparticle cohesiveness and the type of sedimentation that may exist. Totally discrete
