Over the third quarter of physical science we have discussed heat, energy, electricity and magnetism. I have decided to do my paper over these four topics. If you have any questions please hold them till the end. First let’s start with heat. We think of heat as to be warm but if you ever get the chance to ask a scientist he will tell you that science defines it as the flow of energy from a warm object to a cooler object. Like when you rub your hands together when you outside at a bomb fire and its cold. When you rub them together what happens? That’s right they get warm. When you rub your hands together they form an energy which is the result of the atoms or molecules in your hands that make your hands get warm. Your atoms, molecules, and ions are always moving bumping into each other or vibrating back and forth and this creates heat. Same with colors have you ever noticed if you wear that favorite black shirt of yours in the sun but you’re burning up. Yet your friend next to you is wearing white and the heat doesn’t seem to bother him. This is because white attracts heat...
In the twentieth century the medical field has seen many changes. One way that hospitals and nursing specifically has changed and implemented the changes is by pursuing accreditations, awards, and recognitions. The purpose of this paper is to understand Magnet Status and the change required by hospitals to achieve it.
For hospitals to reach their peak in the healthcare world they must work to achieve a prestigious credential by the American Nurse's Credentialing Center ( Truth about nursing). In order to receive such a credential, hospitals must fulfill a set of criteria that will take a lot of work and reform within the hospital itself. To receive magnet status hospitals have to express the fourteen forces of magnetism along with the strict list of requirements (Flores, 2007). Magnet status along with everything has its benefits along with its problems. This credential has been researched in depth, and some research feels that certain thing should be changed in order for magnet hospitals to be the best they can possible be. Lastly, there is no doubt that magnet status is of great value because of how it transforms hospitals from great to greater.
The Magnet Recognition Program was initially developed to attract and maintain nursing staff. According to American Nurses Credentialing Center’s (ANCC) web site, the program “was developed by the ANCC to recognize health care organizations that provide nursing excellence. The program also provides a vehicle for disseminating successful nursing practices and strategies.” Nursing administration continues to have an integral role associated with the demonstration of excellence in achieving the highest honor of nursing distinction. The exploration of force one, quality of nursing leadership, continues to be the foundation of magnet recognition.
When it is summertime and I go on a run, my parents say, “Make sure you wear a light shirt!” Once, I asked why, and they said it was because the light colors don’t absorb as much heat, so I wouldn’t be as hot. The opposite was for cold weather. When I had to go outside for a while in the cold, I made sure to wear a black or dark top, because then it would absorb more heat and keep me warmer. I have always been curious about how this works, and if it works, for that matter (Parents can be wrong, you know). Also, the concept of energy simply intrigues me. This is why I decided to find out more about how colors on a shirt, or anywhere else, can affect temperature. When I started my research, the literature (or scientists) explained that a color will, in fact, affect the temperature of that object. This temperature is measured by using an infrared thermometer and a couple of large math equations. With this information, one can then calculate the rate of energy absorption of each color.
Conduction, convection and radiation are the three methods through which heat can be transferred from one place to another. The (www.hyperphysics.com) first method is the conduction through which heat can be transferred from one object to another object. This process is defined as the heat is transmitted from one to another by the interaction of the atoms and the molecules. The atoms and the molecules of the body are physically attached to each other and one part of the body is at higher temperature to the other part or the body, the heat begins to transfer. A simple experiment through which conduction can be understood easily is as follows. First of all, take a metallic rod of any length. Hold the rod in the hand or at any stand made up of the insulator so that the heat does not transfer to the stand. Heat up the one end of the rod with the help of the spirit lamp. After sometime, touch the other end of the end, the other end of the becomes heated too and the temperature of the other end of the rod has also increased. Although only one end of the rod is heated with the spirit lamp, but the other end of the rod has also been heated. This is represents that the heat has been transferred from one end of the rod to the other end of the rod without heating it from the other end. So, the transformation of the heat is taking place. This process is called the conduction. Conduction is a process which is lead by the free electrons. As the conduction happens occurs only in the metallic materials, the reason for it is that the metals has the free electrons and they can move freely from one part of the body to another part of the body. These electrons are not bounded by the nucleus so, they can move easily. And when the temperature of the ...
Essentially every single device that humans use to make their life easier can be greatly attributed to the field of physics for its inception. The laws of physics govern everything that we use, see, and observe life as we know it would not be possible without it. Multiple branches of physics exist, but one stands out as the branch that has the most promise to deliver devices well beyond even our wildest imagination, electricity and magnetism. Someone who has not been educated a great deal on the topic usually will not realize how big of a role electricity and magnetism play into their everyday life, and even life on earth. The phone they carry in their pocket, the invisible magnetic field of the earth keep life sustainable, and even the electrical signals that his or her own heart uses to pump blood to distribute throughout the body are all applications of the physical laws of electricity and magnetism. On the horizon lie endless amounts of other futuristic applications that physicists and engineers work tirelessly day after day on. If science is correct in its predictions of the future, electricity and magnetism will play a monumental role in shaping life on earth in the not so distant future.
Light is both part particle and part wave. Light is “the electromagnetic radiation that may be perceived by the human eye”. It consists of photons, which are massless bundles of concentrated electromagnetic energy. Light’s lower frequency is red, and the higher frequency is blue. Like sound, light has frequencies humans can’t detect. Ultraviolet light is at a frequency higher than violet, and infrared is at the frequency lower than the red of visible light. We get UV (ultraviolet) rays from the sun, and infrared is used in night vision to see better.
Colors. Colors are grouped according to their wavelengths. Colors with longer wavelengths such as red, orange and yellow are perceived as warm colors. Colors with shorter wavelengths such as blue, purple and green colors are perceived as cool colors. White, grey and black colors as perceived as neutral colors.
Heat energy is transferred through three ways- conduction, convection and radiation. All three are able to transfer heat from one place to another based off of different principles however, are all three are connected by the physics of heat. Let’s start with heat- what exactly is heat? We can understand heat by knowing that “heat is a thermal energy that flows from the warmer areas to the cooler areas, and the thermal energy is the total of all kinetic energies within a given system.” (Soffar, 2015) Now, we can explore the means to which heat is transferred and how each of them occurs. Heat is transferred through conduction at the molecular level and in simple terms, the transfers occurs through physical contact. In conduction, “the substance
There is an abundance of ways light and color can play tricks with how your body thinks. Color has an impact on everything. When you walk into a restaurant and instantly become hungry is one way that color has an influence. When you feel antsy in one room and calm in the other is another way that color has an effect, this is all because of the atmosphere of that room, which is altered by color.
Light is what lets you experience colour. The pigment of the retina in your eyes is sensitive to different lengths of light waves which allows you to see different colours. The wavelengths of light that humans can see are called the visible colour spectrum.
The Earth’s magnetic field is a major component to exploring the earth. The north and the south poles have always been a guide for travelers. Using compasses, the direction of the north pole and the south pole has always been provided by the magnetic force of the magnetic field. What many people do not know though is the earth’s magnetic field provides way more than that. The magnetic field, also known as the magnetosphere, protects us from all kinds of harmful substances. Some of these substances include solar wind and harmful radiation from the sun. The magnetosphere also protects the atmosphere, which protects us.
Magnets are stones that produce magnetic fields. The magnetic field is invisible, but is responsible for the most noticeable aspect of a magnet: the attraction of a metal object or the repulsion of another magnet. Magnets are used in common everyday household items: credit cards, TVs, speakers, motors, and compasses. A magnets strength is measured by its magnetic moment. (“Magnetism”)
Temperature has a large effect on particles. Heat makes particles energized causing them to spread out and bounce around. Inversely the cold causes particles to clump together and become denser. These changes greatly F magnetic the state of substances and can also influence the strength of magnetic fields. This is because it can alter the flow of electrons through the magnet.
When you were young, you may have remembered about trying to make objects stick together or move things, like metal paperclips, just by using a magnet. Back then, you probably thought that magnets’ only exist as play things. But, now that you’re older, you’ve realised that these objects play a significant role in day-to-day life.
