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

Some would say that Steve Jobs‚ co-founder of Apple Computers Inc.‚ was an exceptional leader. However‚ there are many who would disagree with that statement. Jobs could define leadership in some aspects‚ yet he fell short in others. Jobs’ leadership style is difficult to pin down because his position fit very many styles. Steve Jobs co-founded Apple in 1976 and in 1984 he created the Macintosh‚ the first small computer with a graphic interface. Unfortunately in 1985 Jobs was forced to leave after

The third key difference is‚ manager asks how and when‚ whereas‚ the leader asks what and why. The manager often focuses on survival Whereas‚ leaders mostly look for success (Rao‚ 2010).

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

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

Tony was appointed as the HR manager for tangerine center Sdn Bhd. A beauty center that catered solely to ladies in the town of Kuantan .The beauty center was doing well and the number of clientele was rapidly escalating. The growth was expected to continue and plans were being made to expand the center. This expansion concerned Tony. In the previous year itself‚ Tony had struggled to recruit enough qualified job applicants. He knew that the new expansion would intensify the problem. At that time

Experiment No. 3: Specific Gravity ABSTRACT : Determination of specific gravity is very essential in our study because it is commonly used in industry as a simple means of obtaining information about the concentration of solutions of various materials such as brines‚ sugar solutions and acids. There are many apparatuses that can be used to determine specific gravity depending on the material to be measured. The objectives of this experiment is to make acquainted the different instruments used

Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above

here to present to you about my specific fear. Fear‚ the mere sight of the word makes us cringe. It is a feeling we have all dealt with at one time or another. It is a feeling that we first experience when we are small‚ and are conditioned to respond to in many different ways. Some of us live in constant fear; of accidents‚ of bad people doing us harm‚ or of physical ailments. Everybody in the world which we reside has a fear of something‚ including me. The specific fear of mine is the moment when
