Physics 2426 Date 9/19/2011 Experiment: Electrical Method Mechanical Equivalent of heat Group No 2 Objectives The objective of this experiment is to determine experimentally where the heat comes from and how is it created; also to understand what the relationship between mechanical energy‚ electrical power and joule heating coming from a resistor submerged in water. Furthermore comprehend how to use an electric circuit depending on the use of an ammeter or a voltmeter using a parallel

PHYS 124 – 3:30 Th Lab 5: Joule Heat John Doe 4/3/2014 Introduction The objective of this lab is to learn that whenever there is an electrical current in a conductor‚ there is some electrical energy that is converted into heat energy. The heat generated in an electrical circuit is commonly referred to as joule heat. Sir James Joule studies of these separate phenomena lead him to the discovery of the proportionality constant known as the Joule equivalent of heat‚ denoted by J. The Joule equivalent

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:

OUTLINE - PRESENTATION 1 Title: Peanut Allergy Specific purpose: To inform my audience about the peanut allergy. Central Idea: There are many causes that can occur from the peanut allergy such as direct contact‚ cross-contact and inhalation. Introduction Attention Getter: Jock Roy‚ 55‚ a businessman from Hanover‚ has suffered from peanut allergies after he bit a peanut butter sandwich at a birthday party nearly 50 years ago. He described his reactions as beginning

Lab Report Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased. Procedure: 1. Set up the stand and bunsen burne. 2. Go to crucible heat oven to obtain a crucible. 3. Weigh the crucible and lids mass. 4. Break up the magnesium ribbon on the crucible and weigh the mass of the magnesium‚ crucible‚ and lid. 5. Place the crucible on the ring stand over the flame. Allow

All four Peanuts characters take different approaches to their assignment. Though most finish successfully‚ they all encounter problems on the way that influence the direction their report takes. All begin by saying “Homework‚ yuck.” None of them enjoy the Lucy attempts to write whatever comes to mind with some nonsense included. More focused on the word limit‚ she attempts to write several fillers with whatever comes to her mind. Though what most of what she writes makes sense‚ she ends up pausing

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules
