Abstract The purpose of this experiment was to identify whether density is an extensive or intensive physical property. By using water displacement‚ the volumes of the paper clip samples were measured and the masses were obtained by using an electronic balance. Each mass and volume was unique to their sample so by using their values‚ density was used to identify substances in the lab. After conducting the experiment‚ the results showed that there was a positive slope between the different paper

Lab No.1: density‚ accuracy and precision Aim: to determine the relative precision and accuracy of different glassware items by calculating the density of a known substance. Introduction: the density of a substance is its mass per unit volume. (where P-density‚ m- mass and v- volume). Different materials usually have different densities and densities vary according to the pressure‚ temperature and purity of a substance. When measuring‚ there is always a small uncertainty or error and therefore

We first were asked from our laboratory instructor to attain an unknown solid and were asked to note down the number of the solid. 2. Determine the mass of the unknown solid to the

Experiment: determination of densities Introduction The density of a sample of matter represents the mass contained within a unit volume of space in the sample. For most samples‚ a unit volume means 1.0 ml. The units of density‚ therefore‚ are quoted in terms of grams per milliliter (g/ml) or grams per cubic centimeter (g/cm3) for most solid and liquid samples of matter. Density is often used as a point of identification in the determination of an unknown substance. The density of the unknown might

Gravity is the force that keeps objects close to the earth Not only does gravity keep objects close to the earth it also keeps the solar system revolving the sun Gravity was discovered by Isaac Newton Acceleration of objects that is due to gravity on Earth is 9.8 m/s Also‚ according to Mr. Newton’s First Law‚ once the egg was moving‚ it didn’t want to stop. The container of water interrupted the egg’s fall‚ providing a safe place for the egg to stop moving so you could recover it unbroken

earth; gravity. Whenever I think of gravity‚ the same questions never fail to come to mind. What exactly is gravity? Could human life possible go on without gravity? How exactly does gravity work in terms of numbers and formulas? How was gravity truly discovered and defined‚ and by whom? Gravity is universal‚ and it not affects earth and its inhabitants‚ but also the entire nebulous of stars and planets. Gravity is the force that pulls all things toward the center of the earth. Gravity holds your

Throughout the lab I found out that both of the small and large silver rod‚ do not have the same density‚ and also found out that the gold rod is not real gold. My hypothesis is that since‚ the large and small silver rod has about the same density I believe that they would have about the same amount of volume. They both

PHYSICAL PROPERTIES: DENSITY Introduction According to the definition Density is the physical property that allows us to compare the mass of substances for a specific volume. In this Lab activity that took place in Deree College‚ Agia Paraskevi Campus we deal with the density of solids and density of liquids. The main purpose of this experiment is to understand what in reality density means‚ how we can measure it‚ how useful it is‚ what is the difference between density of solids and liquids

Design Rationale It is known that the acceleration due to gravity (or g) is approximately 9.8m/s2 [down] or -9.8m/s2 [up]. What we are trying to do is design an experiment to measure and confirm this value. Our plan was to drop an object from a reasonable height and use a ticker tape timer to measure the amount of time and distance travelled between each time. The weight of the object used would have to be heavy enough that it would not be affected by air resistance. For example‚ you shouldn’t use

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive
