   # Physics Lab Report: Specific Heat

Satisfactory Essays
Specific Heat: The specific heat is the amount of heat per unit mass required to raise the

temperature by one degree Celsius. The relationship between heat and temperature

change is usually expressed in the form shown below where c is the specific heat. 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.

Abstract: In this experiment we are trying to determine the specific heat of a metal. We

will determine the specific heat from a mixture. We are going to bring several objects of

different temperature together. Thermal equilibrium method would be using for this

experiment. The heat lost by the hot object will be gained by the cold object. The system

we would be consider for this experiment is insulated. In this experiment we will be

putting the hot metal in a calorimeter of cold water.

Specific Heat Lab Report “Here are the facts we confront; No one is against conservation. No one is against alternative fuel sources.” – J. D. Hayworth Research Question: Does the number of hydrocarbons that a fuel is composed of affect how much it will ignite? If so, consider the following: What is the quantity and concentration of the combustion that is released and how can that be measured in other (more coherent) means? These are the fuels that were seasoned throughout the…

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…

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…

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…

Calorimetry and Specific Heat Tessa Williams Chemistry 111 11/13/13 Abstract: In this experiment, the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. The average specific heat of the unknown metal was 0.197˚C and was determined using a calorimeter. The density of the unknown metal was 6.57 g/mL and was determined using a cylinder and displacement. Using the specific heat value of the unknown metal and its density, it…

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…

AIT Physics 1 Honors Laboratory: Specific Heat and Conservation of Energy When energy in the form of heat Q is added to a material, the temperature of the material rises. Note that temperature, in units of degrees Celsius (°C) or Kelvin (K), is a measure of how hot or cold a substance is, while heat, in units of joules (J) or calories (cal), is a measure of its thermal energy. 1cal = 4.19J. A measure of the efficiency with which a substance can store this heat energy is known as specific heat capacity…

Aim: i) To find the relationship between supplied energy and change in temperature of water. ii) To find the specific heat capacity (SHC) of water. Hypothesis: As time increases so does the temperature since the water is exposed to the heated wire for a longer period of time. Variables: The Dependent Variable is the temperature of the water, and since the Energy is calculated using temperature it is a dependent variable as well. The constant variables are the voltage and current. Theory:…

Introduction Specific heat is defined as the measure of the ability of a substance to change temperature. Specific heat of a substance is the heat needed to change the temperature of 1 gram of a substance once degree Celsius. The more Joules (unit of heat) needed, the higher the specific heat will be. The goal is to determine specific heat of a soil sample as compared to water. This difference has many ramifications regarding our climate, with local and global. Hypothesis I predict that after…

vibrating around, the hotter the object feels. We can sidestep this molecular picture by dealing with objects as a whole, and treating the energy transfer as the flow of heat, rather than kinetic energy transfer among particles. |Specific Heat for Various Materials | |Material |Specific Heat | | |(J/kg C°) | |Water |4186 | |Aluminum |900…
