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

ARGUMENTS VS EXPLANATIONS EXPLANATIONS An explanation is a group of statements that try to show how or why something is or will be the case. Specifically‚ we use an explanation when we try to explain what makes a claim true. The event or the phenomenon in question is usually accepted as a matter of fact. Explanations do NOT prove why something is the case. Every explanation is composed of two parts: The explanandum (a statement that describes the event that is supposed to be explained)‚ and

Or at least that is what the media would have you believe. On average‚ it is believed that pit bulls kill 19 Americans per year. The real question that should be considered‚ but that usually is not‚ is exactly what is a “pit bull”? Generally speaking‚ when someone utters those two little words‚ the breed that

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

reading and evaluating six articles written by experts on obesity‚ the data seems to imply that better educating people about how their behavioral lifestyle choices effect their future and current health is the best solution. The six journal articles evaluated and analyzed include: David Freedman’s article‚ “How to Fix the Obesity Epidemic‚” published in Scientific American in 2011. Green Gregory’s article‚ “Physical Activity and Childhood Obesity: Strategies and Solutions for Schools and Parents‚” published

Variable Causes of Childhood Obesity Can childhood obesity be eradicated by diet and exercise alone? While this question may cause some to ponder‚ many will undoubtedly say yes. Yet‚ when we consider that childhood obesity is at epidemic levels worldwide‚ the answer should cause us to proceed unbiased and with great thought. The assumption that high caloric diets and sedentary lifestyles is the only road to obesity is a misconception. Social Cognitive Theorist Albert Bandura defines

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

discussion or magazine articles that are online. I decided to look at dieting and obesity for my research task. I first thought about whether or not I thought dieting was good for a person and decided that it wasn’t good for people. Then I started to research more and found that what I believed was right. Dieting isn’t good for a person because once you lose weight; you put it back on when you stop. I then looked at obesity more closely. I researched it to discover what it was and how it could be treated
