Physics Investigatory Project

The study of science is Physics. Physics means the natural science which involves the study of things made up atoms or matter, and along with related concepts such as energy and force. The experiment is Physics because we are using heat from the sun, and transferring the heat to the oven. So heat or thermal energy is the measure of the amount of energy that is contained in a material. Heat depends on how much of the material, which would be sunlight, you have: if you have twice the amount then normal of whatever you are testing, then you have to double the amount of heat you have. “Temperature is a measure of the ability of a substance, or more generally of any living or nonliving subject, to move the energy made of heat to another living or nonliving subject.” “But we need to remember that light slows down has it goes farther from the sun, and bends toward the normal and has a shorter wavelength when it enters a higher value medium (A substance that makes it possible for the energy to move to one location to another)”. “ Also a light wave is transverse (they can be polarized).”

Q.11) “The Model of the Sun” is a theoretical description of the Sun’s interior derived from calculations based on the laws of physics. It also explains how the energy from nuclear fusion in the Sun’s core gets to its photosphere. (DTU 10ED Page 329)

This problem that i have decided to solve is very significant to me and many other people although most don’t know that in about four states in the U.S an estimated amount 700 people in the U.S without homes die each year. The Science that I used is the science of solar power. I know that the sun is attracted to the color black so I painted the inside of my project black. Also that Insulation covered in a very thin metal sheet makes heat right away when the sun touches it. I got the idea to build my prototype from a website named build it solar here is the link,

Passive solar heating designs are some of the simplest forms of incorporating solar energy into your daily home life. Passive solar designs incorporate the sun

Introduction Calorimetry is to capture energy; you can find both joules and calories from it. This experiment is to show which type would capture energy the best. You will need to know the specific heat of water, as well as the equations to preform this expirement. Purpose

Page 5:When Mr.Baker got to the store he went to the appliance isale and looked around. The first oven he had ever seen was a not a new oven but a oven that saved energy and transferred electrical energy to thermal energy. Mr.Baker did not understand what this meant, so he asked the store clerk what this meant. “This meant that the electric in powers the oven and it turns into heat and it also uses a lot less than a lot less power to heat up,”explained the clerk.

Today, "going green" is by all accounts the catchphrase on everybody's lips. Everybody from America's Next Top Model to auto organizations are hooking onto that to demonstrate that they are regarding our surroundings. Cooking with a solar cooker is one all the more way that you also can practice environmental safety! A solar cooker, or solar oven, is a system that utilizations daylight to cook sustenance as opposed to power or gas. Frequently they are utilized to cook outside, and can be a fun expansion to any outdoors trip. Past only being fun, they are perfect on the off chance that you don't have entry to fuel for your cooking.

Did you know you can cook entire meals without any electricity or gas? It 's true. If you have access to the sun then you can cook with it. Cooking with the power of the sun is commonly referred to as solar cooking, and you don 't need expensive gadgets or equipment to do this successfully either. Solar cooking requires sunlight of course, a bit of time, a few everyday items, and a willingness to experiment. In the most basic form, solar cooking can be done easily as long as you have decently strong sunlight for a few hours. The stronger your sunlight is of course, the easier your solar cooking will be. In the desert southwestern areas of the United States for example, you can literally just lay food out in direct sunlight in the summer and it will cook quickly for you. We 're going to look at a little more than the basics here though. There are two primary ways to cook food with solar power. One is to use what 's known as a parabolic cooker, and the other is to simply use reflectors. A parabolic cooker is actually just anything you have on hand which has a slightly bowled, or parabolic shape to it. Round satellite dishes are excellent examples of this type of inward curved surface. The slight curve of a surface like this will allow you to concentrate the natural heat of the sun onto the food you 're cooking. Parabolic cookers can be made with simple cardboard, or any slightly concaved material such as an old (small) satellite dish, a small wok, or even a bent and

Passive solar design consists of taking natural solar energy, such as that from the sun, and using it to our own advantages such as heating or cooling a building. This technique utilizes the sun's heat energy and is important in architectural designs becuase it can have an impact on bettering the environment. An example of this could be larger window placements on buildings based upon the location of the sun as well as taking into consideration the different season of the year.

Introduction: The theory behind this experiment is the heat of a reaction (∆E) plus the work (W) done by a reaction is equal to

In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.

Solar energy is the most plentiful and purist renewable energy source available. Because it is completely natural, it is considered to be a clean energy source. It does not disrupt the environment or threaten the Eco-systems the way oil and some other energy sources tend to. Nor does it cause greenhouse gases, air or water pollution. Solar energy is an immensely important aspect of life and has been since the beginning of time. Increasingly, we are learning how to harness this important resource and use it to replace traditional energy sources. Modern technology can utilize this energy in a variety of ways, such as; generating electricity, providing light or a comfortable interior environment, and heating water for domestic, industrial, or commercial use. One day solar energy may well become our primary form of energy. This would lead to a clean environment, less money spent on utilities, and a healthier world. It is highly important because it has the potential to allow technology and nature to co-exist peacefully.

Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.

Introduction: Every chemical change is accompanied by a change in energy usually in the form of heat. If heat is evolved, the reaction is exothermic, and if heat is absorbed, the reaction is endothermic. The energy change of a reaction that occurs at constant pressure is called the heat of reaction or the enthalpy of reaction (ΔHr). This quantity of heat is measured experimentally by allowing the reaction to occur in a calorimeter. In this experiment you will determine the heat of neutralization when an acid and a base react to form 1 mole of water. In a perfect calorimeter, heat is exchanged only between the reaction and the calorimeters water. Technically, some heat may may be absorbed the calorimeter. All calorimeters exchange some heat with its environment. This amount of heat is called the calorimeters heat capacity (the amount of of heat required to raise its temperature 1∘Celsius). We are going to “pretend” that our calorimeter is the perfect calorimeter.

Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.
