Potential energy

The total change in energy is equal to the sum of the net reaction that is Hess’s Law the way I see it. It is important because it shows how energy is moved whether absorbed or released which is critical in science where logic and reason define all knowledge derived from the implications of science. Hess’s Law is used to determining difficult to measure energy changes such as the generation of hydrogen as a clean fuel in the example given in chem wiki (Shelly Cohen October 02 2013). It is also…

LAB REPORT 1 MEASURING ENERGY EXPENDITURE USING CYCLE ERGOMETER 10/13/2015 SHEETAL PARMAR TY2 INTRODUCTION Physical activity is defined as movement of body, which is produced by the skeletal muscles of the body which results in energy expenditure. There are several numbers of techniques for the assessment of physical activity related energy expend, the most valid technique to estimate this value at the definition of the physical activity is indirect calorimetry (Westerterp, 2013).…

different forms of energy and work. Not only does the thermodynamic state define volume, temperate and pressure, it will contain heat sources giving a capacity, and change state. The idea of thermodynamics is for the system to adjust itself back into its original state of an equilibrium. Through expressing the laws of thermodynamics, it is apparent that heat energy is important in the world in order to achieve ultimate equilibrium. When given a system, it is states that energy cannot be created…

Most people dread going to their jobs. They hate putting on their plain uniform, and dealing with crabby and ungrateful people, not to mention the drive to work for these people is almost as terrible as work itself. I am nothing like this. Every day before I work, I put on my athletic shorts, t-shirt, socks, and I am excited to start my job. I enjoy my drive to work, and when I get there I am greeted by a few co-workers. I then put my bags in the office, and make my way to the gym. The other…

An individual’s personal goals will depend on what he or she chooses. For instance, a person wanting to gain muscle strength will want more protein. A person who wants to simply lose weight will likely want the fat burner supplements and the energy enhancers. Besides supplements, a person’s eating habits must be changed in order to adequately lose weight. A person needs to purchase healthy options from the grocery store, meaning that they must buy whole grain foods, non-processed foods, fruits…

Average Metabolic Rate Difference of Goldfish in Dark vs. Ambient Light Introduction Metabolism is an interesting field of study to better understand what is happening inside of the body of different organisms that keep them alive. Goldfish (Carassius auratus) were used for this experiment since these small animals metabolism can be easily influenced by different variables. This is due to the fact that goldfish are poikilothermic whose internal temperature is influenced by their surroundings.…

The opportunity for career advancement within the Social Security Administration is what motivates me to work harder, take on more projects, and continuously study the law. It is in the agency 's best interest to have a legal assistant that goes above the call of duty and possesses the talent, legal knowledge, and competencies necessary to not only accomplish the mission but also exceed external customers ' satisfaction. Pursuing my Master 's degree is part of reaching the ultimate goal of…

What is meant by the specific heat capacity of a substance? It is the amount of energy required to increase the temperature of one gram of a body by one Kelvin unit, expressed as J/K/g. The specific heat capacity also can be measured in J/K/Kg and J/K/mol. Substance Specific heat Capacity (J/K/g) Water 4.18 acetone 2.17 hexane 2.26 Compare the specific heat capacity of water with a range of other solvents. The table compares the heat capacities of water and two other solvents. Compare the…

These wings give males a selective advantage; they are able to attract female mates. Similar to migrating birds, the monarch butterflies use the clear benefit of updrafts of warm air, called “thermals” and glide as they migrate, to preserve the energy required for flapping their wings throughout the voyage. Studies show that monarch butterflies that migrate for long distances have evolved significantly bigger and longer wings than their cousins. These long wings have a narrow tip, thereby…
