Volume One

ships, float? To answer this, we have to understand the concept of density, which is the amount of mass something has, relative to its volume. For example, compare a bowling ball to a basketball. The bowling ball is filled with a lot of stuff, whereas the basketball is full of air. The basketball will then be the one that floats, and the bowling ball will be the one that sinks. Next,

Introduction a. The main purpose of the Density Lab is to be able to measure density of different objects whether it is a liquid or a solid. Density is the measure of how much mass in a specific matter. To find the density of a liquid you must find the volume and mass of the liquid. Density and specific gravity go hand in hand by that specific gravity is the density of substance/ density of stand, in this case and most cases the standard is water. You have to use the correct number threw out the calculations

are able to identify the unknown liquid and unknown solid that we are given. In order to get the density of a liquid we are first going to divide the mass of the liquid by the volume of the liquid in order to get us the density. In order to get the density of a solid we are going to divide the mass of the solid by the volume of the solid in order to get us the density of the solid. Next we are going to want to find the boiling point of a liquid we find this by placing a thermometer and test tube into

the problem statement, was to take measurements of the length, volume, mass, temperature, and circumference of different substances. In addition, we were to convert these measurements using the factor label method and complete calculations based on the measurements we took at the six different stations of the lab. Furthermore, we were directed to compare and contrast our calculations with other groups in the classroom. For station one, we were directed to calculate the dimensions of two rectangular

Conclusion The purpose of this experiment was to determine the composition of an unknown cylindrical solid using the property of density. The lab reinforced the formula that p, or density, is equal to mass divided by volume and that the volume of a cylinder is equal to (πr2h)/4. Therefore, the density formula of a cylinder, p=(4m)/(πd2l), was used to calculate the density of the solid, which was computed to be 7.16 g/cm3. After determining this value and doing further research, the group concluded

city is as follows: For the first kilometre, the fares is Rs 8 and for the subsequent distance it is Rs 5 per km. Taking the distance covered as x km and total fare as Rs y, write a linear equation for this information, and draw its graph. Find the volume of a sphere whose radius is (i) 7 cm (ii) 0.63 m 22. In parallelogram ABCD, two points P and Q are taken on diagonal BD such that DP = BQ (see the given figure). Show that: 21. (i) ∆APD ≅ ∆CQB (ii) AP = CQ (iii) ∆AQB ≅ ∆CPD (iv) AQ = CP (v) APCQ

Calculus allows physical laws to be expressed in mathematical terms. In science it is valuable in the further analysis of physical laws in predicting the behavior of physical laws, and in discovering new laws. Calculus breaks into two categories one of those categories is Integral calculus. Integral is a vital form of mathematics. It is used everyday to advance and improve our everyday lives. Besides mathematicians, the use of integral calculus is used in many other disciplines. These disciplines

record it in grams (g). Fill a graduated cylinder with water to ~50mL, and record the exact measurement. Place the metal sample in the graduated cylinder. Record the new measurement and subtract the original from it to get the volume. Record that as well. Divide the mass by the volume, and finally record that number as your density. Next, test the magnetism. Do so by placing a magnet next to the metal and observing if there is a pull. Finally, to test the specific heat, place the metal into a test tube

measurement more accurate. The tool that had the smallest degree of certainty was the dial 2 thermometer because it very wide. This caused the measurement to be harder to make. In Station 4, a spring scale, an electric balance, an analytic balance, and a one pay balance was used. The most accurate tool was electric balance because no calculations or estimations needed to be made. The least accurate tool was the spring scale because the scale kept moving and block couldn't be measured without a basket carrying
