determine the specific latent heat of vaporization for water. Electric power supply = 2 kW. Time taken = 5 minutes. Initial reading of the electronic balance = 685 g Final reading of the electronic balance = 565 g Mass of water vaporized, m = ………… Energy supplied by the heater, Q = Pt = ……….. Specific latent heat of vaporization: 11. Applications of Specific Latent Heat • Drinks can be cooled by adding in several cubes of ice. When ice melts a large amount of heat is absorbed and this lowers the…

try to lengthen the endurance of the run. For most athletes, this is a “wall” that they will strive to get over during every single race, because the “wall” defines the amount of potential energy that each runner has by limitation of energy available to perform. In other words, the higher the potential energy, the less likely a runner will become fatigued and the more likely a runner will overcome the “wall.”…

The pattern of dim lines and hues made when electromagnetic vitality, for example, light, goes through a substance and energizes its molecules. The energized iotas radiate vitality as light. Since every kind of iota emits light having an extraordinary scope of hues, the emanation range can be utilized to decide the substance 's concoction organization. An outflow range is an electromagnetic radiation (EMR, for example, obvious light, a substance discharges. Each component emits a novel unique…

important it is to have a consistent, healthy diet when it comes to critical thinking. Our brains use up to 70% of our calorie intake for the day just from thinking, and that means that our brains are using up whatever energy they are given. If you give your brain inconsistent energy throughout the day, it becomes hard to concentrate and hard to deal with everyday tasks. My current diet is that of no carbs, no alcohol, and tons of fat. I realized that fat takes a lot longer to digest than carbs,…

the highest of my potential and perform to the best of my ability. In the future, it will be important to learn to trade some of my future orientation for the goals of others and for my own present happiness. I will have to trade off my time and my energy in order to help others, which is something I am willing and find pleasure in doing. In addition, sometimes I get so caught up in my goals so that I do not necessarily enjoy the present. Although this is a large part of who I am, I also think…

"When I first went to college, some upperclassmen took me aside and asked me if I wanted to graduate. I said, 'Well, yes, of course, I do! ' Then they asked me what kind of grades I wanted to get. I said that I wanted to do very well. 'Then, you will have to learn to love studying, ' they said." "College is full of distractions, worries and problems. There 's always trouble but if you love studying then you will find a way to do what you need to do anyway, no matter what happens. If you don…

these molecules and atoms make energy in the form of heat from their energy, similar to what your body does when it works out and you start to get hot. Therefore all matter has at least some thermal energy, no matter how small or minute it is. There is different types of energy but this essay is meant to inform readers of conduction, convection and radiation because they all deal with thermal energy. As previously stated, matter has energy but the amount of thermal energy determines the…

the study of heart and its transformation into mechanical energy. It bypasses the molecular details of systems and focuses on the macroscopic levels of mechanical work, pressure, temperature, and their roles in energy transformation. Coined by the British physicist Lord Kelvin, the scale of thermodynamics is measured in units of "K". Zero K, or -273˚ C, would represent absolute zero. Absolute zero is the temperature at which no more energy can be extracted from a substance and no further…

After school jobs are hard but most kids have one and with after school jobs comes a lot of responsibility. You still have to make sure you get all your school work done but still have time to work. Most parents would like to have their kid work but when only school is a priority. Usually when you get a job you need to give up time in your day or activity’s to just fit in school and work. So why is after school jobs such a great idea? School jobs are actually really good for some kids for the…

(1951) reported 26 kJ/mol in the study of oxidation kinetics of galena (PbS) while Stenhouse and Armstrong (1952) reported an activation energy of 20 kJ/mol for the alkaline oxidation of pyrite. Koslides and Ciminelli (1992) suggested that during alkaline oxidation of sulphides, there is a change from chemical (activation energy > 40 kJ/mol) to diffusion (activation energy < 40 kJ/mol) control as the rate determining step when temperature is above 100°C This led them to conclude that the…
