Thermal Energy Research Paper

Great Essays
All things are made of atoms that have constant movement, like five year olds on red bull. So 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 physical state of the matter. It is theoretically impossible for atoms to have no movement, but if they could it would be where the Kelvin scale starts at zero kelvin. …show more content…
I mentioned I was a car guy so this is the best car example I can think of for cars, a radiator taking in cold air which runs through the system, transferring the unwanted heat in the liquid in the radiator to the cold air, making it hot air and spitting that out of the system. The most common example in the real world is a pot with water in it, resting on a burner. The heat made from the burner is quickly transferred to the pot and then heating up the water. The thing that separates this from conduction is that the molecules directly touching the pot receive the energy transferred, and move away quickly, only to be quickly replaced by another molecule that lacks this energy, and moving in a continuous cycle. Continuing on the concrete surrounding the pool scenario mentioned earlier, you decide you want to get into the pool, but it is so big that it has not received enough energy radiated from the sun, so you turn on the gas powered pool heater. Convection does not just deal with a flame to achieve, you could also see it by just simply observing an ice cube melt in your hand, because your hand literally is transferring your body heat to the ice cube. Convection can deal with all physical states, so referring back to the swordsmith example, and are done heating up the …show more content…
The most common example of radiation is the sun. The sun radiates heat in the form of light to the earth. So like I mentioned earlier the pool, it needed to be heated by convection because the sun did not radiate enough energy to the pool. Just like the pool, the intensity of heat that is felt is determined by the earth’s position and how close it is to the sun, which is why we have seasons. The distance of the earth from the sun determines the magnitude of heat. We can also experience this by getting close to a light bulb, the closer you get the hotter it feels. It does not just apply to light production, although that is where it is most common, you can also see it in cars. Say you drive your car for a while, if you open the engine bay, you can literally feel the heat radiating from your car. If it is intense enough, you may not even need to open the hood to experience the heat from the engine. You can also observe radiation when the sun is hot and radiates heat to pavement, heating it up and making the pavement radiate heat and you can even see light bend on pavement if it is hot enough. The simplest example of radiation is holding a beaker of liquid over a Bunsen burner, not in direct contact with the flame. The combustion of fuel from the Bunsen burner releases

    Task-5 a) • Metals Metal structure is made up of crystals of metals which are made up of positive metal ions and these ions are surrounded by a sea of delocalized electrons. To separate these substances from this crystal lattice a lot of energy is needed. In between the positive and negative ions is present a strong electrostatic force of attraction. That is the reason why metals have strong melting and boiling points. In order to slide one layer of the metal ions over the other layer very less amount of energy is used.…

    Internal energy is placed in both atoms and molecules, which makes the atoms and molecules move around. Once the speed of energy changes the molecules’ energy will rise as well (Sullivan, 2007). When temperature increases in the molecules, they begin to move faster, and when the temperature decreases, the molecules move more slowly. They are what hold all energy, which creates the potential heat in an object. The amount of kinetic energy reflects the temperature of the particles that make up a material (Nagel, 2007).…

    In this stasis map paper there is four parts of an argument that will be discussed. This argument process was developed by Aristotle and Hermogenes, in ancient Greece. The four parts are conjecture, definition, quality and policy. Conjecture is the cause and the effect of an argument. Definition is the “What is the nature of the problem/issue?What exactly is the problem/issue?What kind of a problem/issue is it?To what larger class of things or events does it belong?…

    Introduction Most aspects of a cell depend on the fact that atoms and molecules have kinetic energy and are constantly in motion. Kinetic energy causes molecules to bump into each other and move into different places. Diffusion is the random movement of molecules from an area of higher concentration to an area of lower concentration. Cells have selectively permeable membranes that only allow the movement of certain solutes.…

    Question 1 (i) Mean: ‘’The sum of a series of measurements (or numbers) divided by the number of those measurements.’’ (Open University,2015: S104 Exploring Science Glossary, Milton Keynes, The Open University). Scientific Notation: ‘’ A notation that represents any number by expressing it as a number that is equal to or greater than 1 but less than 10, multiplied by a simple power of ten where the index may be positive or negative. Thus, 1.30 × 103 is in scientific notation (because 1.30 is equal to or greater than 1 but less than 10, while 103 is a simple power of 10 where the index is positive). Note, though, that 13.0 × 102 and 0.130 × 104 are not in scientific notation.…

    In reviewing others posts I didn’t see anyone do a post on the suggested example of thermal vents so I thought I would take a look into it. The full term describing this amazing underwater creation is “hydrothermal vents.” Basically these vents are hot springs produced from underwater volcanoes, kind of like geysers that form on land. These vents form where two plates pull apart and lava covers the sea floor forming an entirely new floor than what was previously there.…

    There are three main heat transmitters, they are conduction, convection and radiation. Conduction of heat occurs when molecules increase in kinetic energy, the molecules vibrate and this vibration passes the heat to the surrounding molecules. Conduction only occur in solids. Convection is a type of heat transfer that only occurs with liquids and gases because it involves the liquids and gases physically moving, which a solid is unable to do. Convection happens when there is a difference in temperature between the two parts of a liquid or a gas.…

    Essay On Thermoregulation

    • 737 Words
    • 3 Pages

    Thermoregulation is the process of regulating the internal body temperature of animals within a certain range. Endotherms, such as mammals and birds, thermoregulate internally by generating heat from metabolic processes and are able to keep their body temperature high and relatively constant, adapting to the environment to maintain homeostasis. This type of thermoregulation requires a high metabolic rate, that enables organisms to be more physically active without having to rely on the environment, hence increases evolutionary fitness. Ectotherms, such as reptiles and fish obtain heat from the environment and hence have a slower metabolism and can tolerate fluctuations in their internal temperature. Ectotherms thermoregulate by adjusting their behaviour, for example, laying in the sun or submerging themselves in water (Mrowka & Reuter 2016; Griebeler 2013; Grady et al. 2014;…
