Aim: To find the mass in grams (m) of a paperclip. Apparatus: Procedure: 1. Using a piece of string‚ the external circumference(C) of the small test tube was found and was then used to find A ‚ the cross sectional area of the small test tube A=C24π . 2. The beaker was placed under the test tube after it was clamped on the retort stand to collect excess water. The large test tube was filled with water. After which‚ the small test tube which had a fitted scale was placed inside to float

Conclusion 1: In this first lab we attempted to discover which of the materials given to us were hydrates by heating them and then dissolving them in water. Our results showed that all of our substances were hydrates besides the sucrose‚ sucrose if the only one which did not both bring condensation when heated and dissolve in water‚ which agreed with our hypothesis because we also thought that sucrose was going to be the only one that wasn’t a hydrate. The only error that we may have encountered

Vectors Lab Report ABSTRACT: This lab was about constructing vectors graphically and being able to find the resultant of the vectors. Using a ruler to make the vectors and solving them graphically to find the resultants. INTRODUCTION: This lab was important because it went into higher depth on graphically creating vectors and being able to find the resultants. The structures of these vectors have right angles and have combinations that can look the same‚ yet the angles are going different

Conclusion In this experiment‚ we measured the mass of 4 gasses; oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest

Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However‚ in this lab‚ acceleration was observed under different forces‚ other than just gravity. Therefore‚ depending on how strong the forces being exerted were‚ acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley‚ different masses were attached at the end of the string and the glider was allowed to move on the

Lab #1: Projectile Motion Purpose: To determine experimentally the initial and final velocities of an air powered projectile. Hypothesis: If the angle of the rocket is launched at 45 degrees than the distance and velocity will maximize. Materials: Rocket launching platform Rocket launcher Rocket body Air pump Safety goggles Rubber washer Nose cone 40‚ 45‚ 50‚ 55 and 60 angle wooden blocks Measuring wheel Procedure: 1. The rocket was assembled by the rocket launcher

used in this experiment was the Archimedes ’ Principle. Archimedes ’ principle is named after Archimedes of Syracuse‚ who first discovered this law in 212 B.C‚ he stated that: “Any object‚ wholly or partially immersed in a fluid‚ is buoyed up by a force equal to the weight of the fluid displaced by the object.” It is stated in the principle that objects weigh more in air than they do in

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they

The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis
