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

"genius" in this context redefines the usual perspectives and asks us to stretch our understanding to include the potential capabilities of every learner and what it is that they bring with them to make a unique individual worth developing. In his book Awakening Genius in the Classroom‚ Thomas Armstrong coaxes each reader to examine his or her own belief system and to see "genius" as a conceptualization of the best that we each have to offer. The redefining of a commonly understood word in this way is a

wakenings Part 1: In the movie Awakenings‚ a man named Dr. Malcolm Sayer applies for a job at a hospital in The Bronx‚ New York. As he’s being interviewed it’s obvious that he’s nervous and not comfortable around people. His resume shows how in the medical field‚ he’s mostly spent his time doing research and experiments but never working with humans or psychological problems. The manager hires him anyways and he gets right to work. They give him a patient named Lucy who has been in a catatonic

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

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

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

Theory: When to or more substances at different temperatures are mixed‚ heat will flow from the substance of higher temperature to the substance of lower temperature. The heat flow will continue until equilibrium in temperature is reached. From the Law of Conservation of Energy‚ whatever amount of heat is lost by the hot substance
