An Analysis of the Conservation of Mass and Its Importance in Balancing Equations
Conservation of Mass and the Importance of Balancing Equations Conservation of mass is perhaps one of the most essential concepts in the study of Chemistry. In the early development of science, small changes in mass were not measurable. In late 1774, French scientist Antoine Lavoisier invented the analytical balance to c...

An Analysis of the Nuclear Physics
Nuclear Physics Physics is a rather broad subject with smaller fields and areas of
research that are targeted towards a specific goal. Some of these areas
include other sciences combined with physics to help a new generation which
include biophysics, astrophysics, high energy physics, theoretical physics,
condensed ma...

A Lab Experiment to Find the Molar Mass of an Unknown Substance Through the Calculation of Its Freezing Point Depression
Introduction The purpose of this lab was to determine the molar mass of an unknown substance labeled as “3” by calculating its freezing point depression when compared to the freezing point of the solvent, water. Freezing point depression is a colligative property, meaning that the nature and makeup of the solute is not rel...

The Probability of Particle Detection in Quantum Physics
Young’s double-slit experiment provides evidence that light is a wave. In the experiment, the light diffracts from each slit and the bright and dark interference pattern is seen on the observation screen. When the crest and the trough of one wave match with the crest and the trough of another wave, respectively, there is br...

A Report on the Large Hadron Collider (LHC) and the Large Hadron Collider Beauty (LHCb) Experiment
For this paper I decided to do more research on my initial project which was ‘escaping the universe’. There is not much research being done on this, however when I was doing my project I mentioned a bit about the LHC (Large Hadron Collider). As I said in my project, the LHC is said to be able to give us the first ‘experimen...

A Lab Experiment on Conducting a Direct Shear Test to Determine the Angle of Internal Friction of Dry Sand
Introduction:The direct shear test is carried out on either undisturbed samples or remolded samples. To facilitate the remolding purpose, a soil sample may be compacted at optimum moisture content in a compaction mold. Then specimen for the direct shear test could be obtained using the correct cutter provided. Alternatively...

The Different Ways Sound Travels Depending on Pitch, Range, and Location
Most of our lives are dependent on sound... We use sound to be aware of our surroundings, to communicate, sound tells us when something is dangerous or bad, like in a scary movie and you hear creaky sounds and spooky music. Sound makes us happy or sad. I started band when I was about 11 years old and have played bass clarin...

A Study on Physical Constraints of Objects and Online Objects
Object: Seiko analog wristwatch Constraints are used to reduce the possible actions one can perform on an object. A physical constraint on my watch is its clasp, the fold-over clasp commonly found on metal watches. The clasp is a physical constraint because it limits my options for how to secure the watch. After putting...

A Report on Density and Buoyant Force
For our group project, we are trying to see if an object will float or sink
in certain liquids. If the density of an object is greater, then the
buoyant force should increase. If the density of an object it lesser, then
the buoyant force should decrease. Our three major terms for our project is
density, mass, and buoyant fo...
