1. INTRODUCTION Sir Isaac Newton produced three laws of motion. Newton’s second law of motion states that, “the acceleration (a) of an object is directly proportional to the net force acting on it and inversely proportional to its mass” (VUILLE, 86). This second law can be written into mathematical terms and written as: a = Fnet /m However, the equation above is more commonly seen as: Fnet = ma In these equations a represents the acceleration of the object, m is the objects mass Fnet represents the vector sum of all the forces acting on the object. The Atwood machine is an apparatus that explores the idea states above.
The term Cp is the specific heat of the material (at constant atmospheric pressure). Different materials have different specific heat values. The units of specific heat are : Joules/gram deg – C. In this lab we will find the specific heat value of Zinc and compare it to accepted values.This will do by heating a mass of Zinc up to the temperature of boiling water and placing the hot metal into a cup of cold water. The thermal energy that the zinc loses goes into heating up the water in the cup. By knowing the starting temperatures and the final temperature of the water and the zinc, the specific heat of Zinc may be easily obtained.
Abstract The process of nuclear fission causes the formation of fission products. The source and quantity of byproducts of fission are explained to provide a foundation for a discussion of the effects of fission products. The swelling effect of both solid and gaseous byproducts of fission is explained and the negative effect that swelling has on fuel performance as well as its limiting affect on burnup is described. Finally, potential solutions to deal with the effects of fission products and subsequently allow for increased burnup are discussed. Introduction The quantity of fission products in a nuclear reactor is dependent on the amount of fission occurring, which is directly related to fuel burnup.
Chemical Kinetics: Iodine Clock Experiment Bautista, Lance Ruther E., Tornalejo, Norielle Marie B. Abstract: Is Iodine clock really a clock? In what way do we relate temperature with the rate of the reaction? How about the relationship between the concentration and rate of reaction? In this experiment, the effect of concentration and temperature on the rate of a chemical reaction will be studied. For this experiment, when the temperature increases, collision between the particles also increases.
Background Theory & Physics Ideas When Newton outlined his second law of motion, he did not describe it in the way we use it today. He talked about a property of a moving object that he called its 'motion'. He said that when a force acts on an object for some time interval, its 'motion' would change. Today, we call this quantity the momentum of the object. In fact, Newton's first law could be stated as 'in the absence of unbalanced forces, the momentum of an object will be constant'.
In this process, the original atom will lose two neutrons and two protons, changing the element’s atomic number and mass, and subsequently making it into a different element. My model clearly and simply demonstrates this process due to the fact that it does not over complicate the process. I did not label the parent atom intentionally, to imply that this process can generally happen to almost any charged particle. Also, empty spaces are left in the atom to show that the particles that form the helium nucleus were released. On top of this, the helium nucleus is clearly labeled and is shown containing two neutrons and two protons (which are also labeled using an “N” and a “+”).
Blunt Trauma Lecture Blunt trauma is the most common cause of trauma death and disability. It results from an energy exchange between an object and the human body, without intrusion of the object through the skin. Blunt trauma is especially confounding because the true nature of the energy is often hidden, and evidence of the serious injury is very subtle or even absent. KINETICS- is the branch of physics dealing with forces of objects in motion and the energy exchanges that occur as objects collide. 2 Basic principles of Kinetics are the “law of inertia” and the “law of energy.” Sir Isaac Newton “The law of inertia” also known as Newton’s 1st law helps explain what happens during blunt trauma.
The mole can be also defined as the number of atoms in exactly 12g of Carbon. In this experiment, the magnesium will be heated and this magnesium will react with the oxygen in the air to form magnesium Oxide. DIAGRAM: METHOD: 1. An empty crucible and its lid were weighed on an electrical balance. The mass of the crucible and its lid were recorded.
Paragraph 1 The research paper talks about how the temperature of formation and crystallinity of iron phosphate, FePO4, is critical in determining its electrochemical behaviour. FePO4 is known to crystalline in several different structures. At 600 degrees, FePO4 irreversibly changes into an electrochemically inactive quartz-like structure, which shows that the olivine form is metastable. FePO4 at a high temperature is limited to measurements of call parameters. In the case of α-phase FePO4, cell parameters tend to increase exponentially as temperature increase.
It is useful at predicting reactant and product quantities through a reaction. There is enthalpy, Hess’s Law and is related to thermodynamics. It is applied in the real world by adding ice to water, burning fuel for a vehicle, and when power plants pump water into their machinery to keep them cool and not overheat. 2.In an insulated container, you mix 200g of water at 80°C with 100g of water at 20°C. After mixing, the temperature of the water is 60°C.
