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)
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
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
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
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
Energy is everywhere around us and everywhere you go, it is also the property of all object. When you throw a ball, that’s energy. When you turn on the lights in your house, that’s energy. When you’re charging your phone, that’s energy. Everything you do today, is the cause of energy. There are many ways you can describe energy, and you can use it in many different ways. Energy is one of the most core parts of our universe today. We use it for everything. The definition of energy is to preform work
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
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

increased. The equation to show this reaction is: Zn + CuSO4 ® ZnSO4 + Cu The enthalpy change for the reaction is: ²H = -217kJ mole ¹ This means that if 1 mole of solution is used of each substance, the heat given off will be 217,000 Joules. Apparatus: § 1 test tube § 20ml of copper sulphate solution for each experiment § Zinc § Rubber bung § Thermometer Prediction: I think that as the amount of zinc is increased, the temperature of the solution will also increase
Heat is based on the total internal energy of the molecules a body has. So what’s thought of as “cold” is truly just the absence of heat. Since heat is a way to transfer energy that means it can be measured. The metric unit of heat is a calorie or joule, and in Britain it’s a British thermal unit (Btu). Temperature 3 Temperature is defined as the measure of the average kinetic energy of the particles of a substance. It is not a form of energy but a means of energy transfer. And since it is an
increase of 5.1oC. The total weight of the fluids used is 53 cm3. The density of water is 1g/cm3 so 53 cm3 of HCL and NaOH is equal to 53g 53g x 4.2j = 222.6 joules to raise the temperature of the solution by 1oC. The temperature of the solution was raised by 5.1oC so: 222.6 J x 5.1oC = 1135.26 J This equation shows us that 1135.26 joules of energy were used in
A similar misconception between kids and adults is that Earth’s seasons occur because the United States is closer to the Sun in June and farther away from the Sun in December. On a recent survey, 49% of kids and 59% of adults said that the United States is closer to the Sun in June, and farther away from the Sun in December. In June, the United States is 153, 000, 000 kilometers away from the Sun, and in July the United States is also 153,000,000 kilometers away from the Sun. In December, the United
nitrogen vaporized, leaving less in the cup with the water. This would in turn, make the water not reach the lowest temperature that it should have reached because the water and the cup didn’t have as much nitrogen energy to consume. This would make the joules of heat released less, as well as the heat of vaporization values I obtained lower than the theoretical ones. Since the measured heat of vaporization was less than the accepted one, it caused my percent error to be negative. My second unique error
Percentage elongation (ductility) of the joint decreased due to the post weld heat treatment. • From the results of the Charpy V-notch impact test, it is found that the maximum CVN value in as welded condition of low heat input combination is 115 Joule, and it is increased with the post weld heat treatment. • Comparing the joints welded with two different heat inputs, concluded that the ultimate tensile strength (UTS) and impact toughness of the welded joints decreases with increases the heat input
