Experiment #1: Mass‚ Volume and Density Performed: 2/2/11 Turned in: 2/9/11 The purpose of this experiment is to verify the independence of X and Y motion for a projection. We watch the professor perform this experiment. The equipment used in this experiment was a projectile launcher (ME-6800)‚ a drop shoot accessory (ME-9859)‚ one photogate (ME-9204A)‚ white paper‚ carbon paper‚ two time-of-flight timing pad (ME-6810)‚ two balls (ball 1 and ball 2)‚ and an interface computer. Ball 1 is dropped

In part A of the experiment the two values obtained for the specific heat capacity of the metal were about .0500 J/mol. This is a large deviation‚ with both of these values identifying very different metals. The average heat capacity identified the metal used as brass. The average heat capacity calculated was .3776 J/mol and the actual heat capacity of brass is .375 J/mol. The second run displayed the closest value to the actual value. A source of error that may have caused a large divide in the

Soil Porosity & Density Objective: To determine if the porosity of soil is related to the density. Hypothesis: I think that that the porosity of soil is related to the density because the higher the density of the sand the lower the porosity of the sand‚ which are both componets for the water to rise. Materials: • Sand and Loam samples • 2 large containers • Plastic cups • Water • Scale Procedure: Loam 1) The loam without the water was fresh ‚ it had different shades of black‚ and

Ten Minutes of Specific Heat Remi Adams East Rowan High School AP Environmental Science Abstract Specific heat and climate were the primary focus of this lab. Specific heat is defined as “the measure of the ability of a substance to change temperature”. The purpose for carrying out this lab was to determine the specific heat/rates of both soil and water‚ and then comparing them. Students also were to relate specific heat to climate. Students were to determine which substance expressed

Report of Density Determinations Density is defined as the mass of substance per unit volume. Both pure substances and solutions are applicable. Today we are going to determine the Density of rock chunks and NaCl solution. In this experiment‚ we will determine the mass and volume of each object and then we will calculate the ratio—the density. In the first part of the experiment‚ we should measure the density of some irregularly shaped chunks of rock. The Weight of rocks is 18.769g

Specific Heat Lab Objective: Find the specific heat of the unknown metal given using calorimetry. Background Theory: In every reaction‚ energy is transferred between a system and its environment. A system encompasses the substances that are involved in a reaction‚ and everything else in the universe other than the system is called the environment. The standard SI unit of energy is Joules (J). Temperature is the level of excitement of the atoms in a substance. In most cases‚ energy is

Specific heat is the property of the material that an object is made of. The greater the material’s specific heat and the mass‚ the more energy must be added to change its temperature. The goals of this lab were to calculate the specific heat of water and compare to the known value of 4.19J/°Cg. Another goal was to calculate the efficiency of the hot pot used for the experiment and to estimate the cost to heat water for a cup of tea and to bath in a bathtub. The thermal energy E= cm Δ T‚ required

Name Date Lab: Denisty – Solids and Liquids Part 1: Density Background Information: The density of an object is how much “stuff”‚ or molecules‚ a substance is made of. Density is how tightly packed the molecules are. To calculate the density of a substance we need to know the mass (weight) of the substance and the volume (how much space) of the substance. Mass is determined by weighing an object. Volume of regular shaped objects is calculated by measuring

Discussion Based on the results of the lab it can be seen that the metal in the lab can be identified as lead. The identity of the metal was determined by the heat energy calculations. The heat capacity that was found matched closely to that of the lead. There were several possible sources of error that could be found throughout the lab. Some of the main errors as seen in question 7 that could have affected the results of the lab were the amount of water transferred with the hot metal‚ the
