Marybeth Brooks Physics Lab III Specific Heat Capacity Lab May 25‚ 2011 Abstract The specific heat capacity of various metals can be calculated and compared to accepted literature values. Dropping heated metal samples into a calorimeter filled with water and then measuring the change in the temperature of the system accomplished this. The metal samples were heated in a boiling water bath and were assumed to be at 100 C when they were removed. It was added to a calorimeter and stirrer

mind when thinking about the new laws that have been passed against pit bulls. After years of discrimination of people‚ we are now discriminating against breeds of dogs. Even though aggressive dogs tend to bite more‚ I am against the idea of breed specific legislation because it is not the breed of the dog but how it is trained. There are many advocates for BSLs‚ including the leader of PETA (people for the ethical treatment of animals). This is an excerpt from the leader of PETA‚ Ingrid Newkirk‚

the hot metal wouldn’t effect the specific heat capacity of the metal. The amount of water wouldn’t change the temperature‚ so the heat capacity wouldn’t be changed. The metal cooling off could change the heat capacity because the temperature wasn’t kept constant and would most likely lower the calculated value of the specific heat capacity. The calorimeter losing heat as a result of stirring would most likely raise the calculated value of the specific heat capacity. The surroundings are

Conclusions The purpose of this experiment was to find the relationship between a substance’s specific heat and its atomic weight. In the lab‚ the substances with the higher atomic weights had less specific heat. From this‚ we can conclude that specific heat and atomic weight have an inverse relationship‚ meaning as one decreases the other increases. The reason for this is because if atoms are small‚ or light‚ they have the ability to pack tightly together‚ leaving almost no space between them

hype and over sensationalism of so called “dangerous dogs” breed specific laws have become an issue within today’s society. Breed specific laws are laws that restrict or completely ban the owning of a dog breed‚ some owners of the breeds must have their dog complete tests as to whether or not it is vicious and the owner must acquire permits to keep possession of their precious family pet. A typical person may think that a breed specific law does not acquire the town that they may live in but virtually

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:

Title: Specific Heat Capacities of Metals Experiment Date: 3/28/2012 Report Date: 4/4/2012 Purpose: The purpose of the lab is to measure the specific heat capacities of aluminum‚ steel and brass. Theory: The amount of heat (ΔQ) required to change the temperature of an object is proportional to the mass (m) of the object and the temperature change (ΔT) of the object. ΔQ= cmΔT where c is called as the specific heat capacity of the material. In the calorie units system the unit of quantity

OPTION B (Punishment) Statistics show that there is a high rate of criminal recidivism in the United States. This raises the question‚ “Does punishment deter crime? · Research the affects of the four types of punishment—retribution‚ deterrence‚ rehabilitation‚ and societal protection—in relation to today’s American society. To help get started‚ try search terms such as “effects of retribution on American society.” · Write a 1‚050- to 1‚750-word paper that summarizes your research
