James Prescott Joule JAMES PRESCOTT JOULE was born at Salford, near Manchester, England, on December 24, 1818. He was the second of five children born to a wealthy brewery owner. James was educated at home until he was 15. He then went to work in the family brewery However, he and his older brother continued their education part-time with private tutors in Manchester. From 1834 until 1837, they were taught chemistry, physics, the scientific method, and mathematics by the famous English

James Prescott Joule was born December 24, in 1818. James Joule was born into the wealthy brewing family of Benjamin and Alice Joule. In 1847 James Joule married Amelia Grimes, a daughter of the Liverpool Comptroller of Customs. James Joule and Amelia had three children: Benjamin Arthur (born 1849), Alice Amelia (born 1852) and a son who died in 1854 along with his wife during child birth. In 1843 James Joule read his paper to the British Association, entitled "On the Calorific Effects

at an even temperature. Prediction/Hypothesis: I think that the Brazil nut will contain the most energy. I did some energy amounts each food has, the results are as below; Brazil Nut: 265000 joules per gram Peanut: 24600 joules per gram Bread: 24600 joules per gram Pasta: 2500 joules per gram Although both types of nut contain high levels of energy, they might contain less of other substances, like protein, for example. Which Bread and Pasta can provide more of. Diagram:

(Holt 73). Energy is transferred or transformed whenever work is done. Work requires an object to experience a change in position or motion but energy can be present even when nothing appears to be happening. Both work and energy are measured in Joules. Work In order for work to be done force has to cause a change in the position or motion of the object in the direction from which the force comes from. Meaning, the object that the force is applied to has to move in order for it to be considered

temperature of one pound of water by one degree Fahrenheit (Kraushaar and Ristinen 13-14) and the Calorie is the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius (1/11/02). A joule is the energy unit for the metric system, and 1055 joules = one btu = 0.252 Calories (1/11/02). Also, we learned that one gallon of gasoline is equal to 124,000 btus, one pound of coal is equal to 13,000 btus, and one cubic foot of natural gas is equal to 1,000 btus (1/11/02)

Energy content is an important property of food. The energy your body needs for running, talking, and thinking comes from the food you eat. For this project I conducted an experiment on different kinds of nuts in which I aimed to determine how much energy were stored in these nuts. The experiment was executed by burning these nuts to heat up a container of water and calculating the change in temperature that takes place. Using the change in temperature, one could calculate the amount of energy set

Introduction This report is based on the investigation and research on reducing electricity consumption of certain appliances and to improve energy usage at home. The demand for electricity in South Africa is increasing and it is exceeding electricity supply, research has shown that households contribute 15% to the countries total electricity consumption [1]. Efficient energy usage is very critical; electricity can be used very inefficiently in households during peak load times. In order to tackle

Capturing Pressure for a Greener Future At this very moment, the amount of cars driving on roads or highways would seem to be an uncountable number. In reality, according to Statistic Brain, the number of cars being manufactured in the world exceeds 48,039,060. This number is not counting commercial vehicles, and due to the high demand for commercial vehicles for today’s businesses, the number can be assumed to be much higher. The typical car will release an exorbitant amount of CO2, which to certain

Executive Summary Load Signature by instantaneous power waveform (IPW) is decomposition of appliance distinctly operates or a load device base on instantaneous power waveform (IPW). In this project, I will try to design a program using software Matlab / Simulink or labview for instantaneous power waveform. It is convenient to convert the raw data collected form power meter to IPW for analysis. This technique can use on power monitoring, power quality and equipment health monitoring and energy saving

Stereotype generally refer to a statement made from members of society or a widely held idea or image about a certain group regarding appearance, culture, disability, etc. Over the years, there have been many stereotypes and labels put on Indians. The movie “Bend it Like Beckham” has shown a lot of such assumptions. The movie uses the life of the main character, Jasminder, to create a representation of Indian Culture. In the movie, both Jasminder and Joule’s mothers hold a stereotype of how women

Butanol: [IMAGE]C4H9OH + 6O2 4CO2 + 5H2O + heat Heat (joules) = T x mass (g) x specific heat capacity ===================================================== Heat energy = rise in temperature x mass of water (g) x 4.18 ============================================================ The specific heat capacity is the number of joules required to raise the temperature of 1g of water by 1oC (1g of H2O raised by 1oC = 4.18 joules) The combustion of the alcohols is not exactly as shown

A french scientist has even invented a lamp of algae, which runs off carbon dioxide and produces oxygen (“Large scale Algae Street Lamps to clean the air off its CO2 content,” 2012). A few companies are researching microalgae biofuel production: Joule Unlimited and the Natural Resource Energy Lab. Methods for finding other strands of microalgae biofuel include natural trial and error testing and genetic engineering (Pienkos, P., et al., 2011). “Algae lamps” and microalgae biofuel are some tools

of paper ... ... for the work: Change in work W= 1.394982 N* 2.089m - 1.372419 N * 2.089m 0.047134107 Joules The total energy needed for the car to pass over the track was 0.047134107 Joules. The total energy that was recovered was 0.0139339205 Joules. They are not equal and the percentage that was recovered was only a fraction of the total. Percentage 0.0139339205 Joules / 0.047134107 Joules = 0.2956 % Currently only 14-26% of the energy you put in your tank is actually used and by using regenerative

When you exercise or actually when you just move, you spend your energies. Energy is needed for the body to move and stay alive and grow to keep the body warm. Energy comes from all the foods and drinks you eat. Things like carbohydrates, proteins and fats are mainly the macro-nutrients. How much energy depends on many things like your gender, body composition, and your activity levels. Energy expenditure is often referred as the sum of the basal metabolic rate (BMR) which is the amount of energy

Investigation of the Amount of Energy Given off by Different Types of Alcohols When Ignited For my investigation I will be finding out the amount of energy given off by different types of alcohol when ignited. To do this I will be burning the alcohol in a small glass burner, with the flame

The fact that our engines waste our fossil fuels by only using only about 30-45% of the energy from gasoline would create an outrage among the people that want to maximize the use of out fossil fuels as they begin to run out. They would call it pure insanity. What will anger them more is that the wasted energy goes off as heat into the atmosphere. Increasing the efficiency is upsettingly and depressingly, near-impossible. What can be done is that we repurpose that heat into something useful! The

Ventricular Tachycardia An dysrhythmia of the heart is an irregular heartbeat rhythm. Ventricular tachycardia is an dysrhythmia in which the lower chambers of the heart, the ventricles, beat unusually fast. The heart rate is measured with an electrocardiogram, or ECG. This is a machine that measures the electrical impulses from the patient's heart. This is displayed on a monitor or ECG graph paper. The boxes on the graph paper measure time. Five small boxes are equal to one large box.

The Zeroth and First law of Thermodynamics The zeroth law, the first law, the second law and the third law of Thermodynamics are the four laws that govern the movement of heat between objects. The zeroth law of thermodynamics states that the temperature of two objects begins to change and after a certain amount of time the change stops at which point the objects are said to be in thermal equilibrium. Putting together two objects at different temperatures will cause the temperature of the hottest

Evaluating An Enthalpy Change That Cannot Be Measured Directly. Dr. Watson. Introduction. We were told that sodium hydrogencarbonate decomposes on heating to give sodium carbonate, water and carbon dioxide as shown in the equation below:- 2NaHCO3(s)--------> Na2CO3 (s) + H2O (l) + CO2 (g) = DeltaH1 This was given as deltaH1 and we had to calculate as part of the experiment. This however cannot be measured directly, but can be found using the enthalpy changes from two other reactions. These being
