Objective:

The purpose of this lab was to calculate the specific heat of a metal cylinder

Procedure:

1. The 100ml Graduated cylinder was filled with water and a rubber stopper.

2. The metal was placed in the Graduated cylinder, water displacement was found.

3. The beaker was filled with water and the metal was placed in the water.

4. The Bunsen burner was lit.

5. The water in the beaker was boiled using the Bunsen burner.

6. The Styrofoam cup was filled with approximately 100ml of water.

7. The temperature of the water in the Styrofoam cup was found.

8. The temperature of the boiling water was found.

9. The thermometer was cooled.

1. The metal cylinder was removed from the boiling water and placed in the Styrofoam cup using tongs.
2. The temperature of the water and the metal cylinder was measured.

Theory:

Theory of Water of Displacement: A volume of water was measured. A second volume of water was measured when the metal cylinder was added. The initial volume was subtracted from the second (total) volume to get the volume of the metal cylinder.

D=M/V M=DV therefore: M=D(T-I)

q=M½DT½Cp qgained=qlost

qmetal=Mmetal(Ti-Tf)Cpmetal qH2O=(DH2OV)(Tf-Ti)CpH2O qmetal=qH2O

therefore:

Mmetal(Ti-Tf)Cpmetal=(DH2OV)(Tf-Ti)CpH2O CpH2O=4.

## Essay on Lab Report: Specific Heat

- Introduction The porpoise of these is to determine the Specific Heat. Also known as Heat Capacity, the specific heat is the amount of the Heat Per Unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature changed is usually expected in the form shown. The relationship does not apply if a phase change is encountered because the heat added or removed during a phase change does not change the temperature. Q = cn^T The molar specific heats of most solids at room temperature and above are nearly constant, in agreement with the Law of Dulong and Petit....   [tags: essays research papers]

## Investigating The Specific Heat Capacity Of Brass Using Calorimetry Essay

- Aim: To determine the specific heat capacity of brass using calorimetry, the understanding of the relationship between heat and temperature and the concept of heat transfer, using the equation; Q=mc∆T. Also to evaluate the data collected by comparing the experimental value to the accepted value using analytical skills. Method: • We heated up a brass weight by immersing it into boiling water for a while in order to assure that the metal’s temperature was the same as of the water. • We then placed the brass weight into the calorimeter and took a series of readings of the temperature of the water inside in order to find the maximum temperature reached....   [tags: Heat, Specific heat capacity, Heat transfer]

## Heat Capacity of An Unknown Metal Essay examples

- Heat Capacity of An Unknown Metal Purpose: The purpose of performing this lab was to find the specific heat capacity of an unknown metal. Hypothesis: Since all metals have different densities and makeups I think that the heat capacity will greatly vary. The makeup of iron is very different than aluminum so the heat capacity will be quite different. Also, a lot of metals are not completely pure and that will also have some effect on the heat capacity. Materials: -Hot Plate -Two (2) Beakers -Water -Metal Objects -Two (2) Thermometers -Pencil -Paper -Calculator Design: A hot plate is acquired and plugged in and if left to warm up....   [tags: Lab, Experiment]

## The Heat Energy Transfers From One Substance Essay example

- Thermodynamics is essentially how heat energy transfers from one substance to another. In “Joe Science vs. the Water Heater,” the temperature of water in a water heater must be found without measuring the water directly from the water heater. This problem was translated to the lab by providing heated water, fish bowl thermometers, styrofoam cups, and all other instruments found in the lab. The thermometer only reaches 45 degrees celsius; therefore, thermodynamic equations need to be applied in order to find the original temperature of the hot water....   [tags: Thermodynamics, Temperature, Heat, Aquarium]

## Essay on Equilibrium Reaction Lab

- IBDP Chemistry IA: Equilibrium Reaction Lab Introduction: Reactions are based on collisions of particles, in which the particles must have sufficient energy. Some chemical reactions are reversible, and when the rate of the forward reaction equals the rate of the reverse reaction, the process has reached equilibrium. As it will appear to have stopped, as there is no overall change due to the rates being equal. Through this lab, we will be investigating one factor that will affect the equilibrium constant....   [tags: Chemistry, Collision of Particles, Reactions]

Research: In today's world, almost everything we do needs power from fossil fuels or waterfalls. This obviously presents a problem for our limited natural resources and our atmosphere. Many alternatives have been proposed and some used. Most, like solar power and wind power, require certain weather conditions not common in many locations. Others, like nuclear power, create waste problems....   [tags: Papers]

## Using Hess’s Law to Calculate Heat of Formation of of Magnesium Oxide Essay

- Heats of Reaction and Hess’s Law Lab Background: Thermochemistry is the branch of chemistry that deals with the amounts of heat evolved or absorbed during chemical reactions. When the pressure is constant, the amount of heat gained or lost in a chemical or physical change is the enthalpy change for the process, or heat of reaction. Heat of reaction can be calculated by using Hess’s Law which states that the heat released or absorbed in a chemical process is the same whether the process takes place in one or in several steps, also known the law of constant heat summation....   [tags: reaction, calorimeter, experiment]

## Lab Report Comparing Oxygen Consumption Rates in Different Mammalian Subclasses

- Lab Report Comparing Oxygen Consumption Rates in Different Mammalian Subclasses The purpose in experimenting with computer simulations was to compare oxygen consumption rates in different mammalian subclasses. We compared monotremes, marsupials, and placental mammals at both warm and cold temperatures. The results supported our hypothesis that when temperature increased, metabolic rate decreased. This was also supported using a student's t-test. We also found that placental mammals had the highest oxygen consumption rates and marsupials had the lowest....   [tags: Papers]

Discussion:

The specific heat of Iron was calculated to be 0.503j/g°c.

The error analysis of this experiment was ç.4494 j/g°c -.5033 j/g°c ç/.4494 j/g°c x 100 = 11.93%

The metal cylinder was identified as iron because the density found was closest to the theoretical density of iron. The experimental data that was calculated was not accurate according to the theoretical data. This could be for various reasons. A mass scale was not used in this experiment. Therefore the volume was found by water displacement and then calculated using the theoretical density, which was 7.874g/ml. The metal cylinder was iron. This experiment could be improved by using a mass scale to find the mass of the metal cylinder.
