The thermoelectric effect refers to phenomena by which either a temperature difference creates an electric potential or an electric potential creates a temperature difference. Conversion between electrical and thermal energy is possible because of two important thermoelectric effects: Seebeck effect (converting temperature to current) and Peltier effect (converting current to temperature). Direct conversion of thermal and electric energy means that the thermoelectric devices are often more reliable than traditional mechanic devices and suffer less wear. Thermoelectric devices have a much lower efficiency than traditions devices. While all materials have a nonzero thermoelectric effect, in most materials it is too small to be useful. However, low-cost materials that have a sufficiently strong thermoelectric effect (other required properties) could be used in application including power generation and

    The nano-thermal analysis method is capable of studying the specific regions of a sample irrespective of its composition. In a multi-component sample, the analysis methods make it possible for the researchers to distinguish between the different components and identify the different characteristics found in each of the sample (Craig, 2002). During the analysis of any sample, the nano-thermal method does not necessarily require the physical alteration of the sample. In its place, it is capable of analyzing any sample through surface studies.

    Three types of heat transfers help solar cookers use the sun’s energy to cook food. Heat is always transferred from the warmer object to the cooler object. Heat is also transferred to and through some materials better than others. The three types of heat transfers are radiation, conduction, and convection. Convection is the heat transfer by movement through materials such as air or a liquid. Materials like these are called mediums. Convection is the primary way heat can be transferred through liquids and gases. To classify a heat transfer as convection, hot air has to rise up to equally heat the air around it. Box solar cookers have to retain this hot air to cook food, so the cookers have to have lids with a transparent covering. The transparent covering shuts in all of the hot air and keeps out the cool air. The second heat transfer is the transfer of heat between two objects, or substances, that are directly in contact with each other. This heat transfer, called conduction is the primary way heat can be transferred through solids. In gases and liquids, conduction works poorly because the atoms have a great deal of space between them. Since they have a lot of space between each other, they can’t communicate heat to one another. The solid, aluminum foil, is commonly used in homemade solar ovens because it is a metal. It is well known metal is a great conductor of heat. Since metal (aluminum) is a great conductor of heat, whatever comes in contact with it will gradually absorb the heat from the metal. The third type of heat transfer is radiation. Radiation is the transfer of energy (heat) through space by electromagnetic waves. Solar energy reaches Earth by radiation (Pearson 485). When an energy wave comes directly in contact with...

    IC Temperature Sensors agreed that there is a major diversity of how thermal sensors read the heat, for example, a thermometer measures temperature with mercury rising as heat increases, showing the temperature on the side. However, thermometers only measure the temperature when it is close up to the heat source. Thermographic sensors are long ranged temperature measuring devices which makes them more ideal for this experiment. Thermographic sensors read the temperature using thermograms. Thermograms show a variety of different shades of color depending the temperature. The temperature is based off a number of different variables such as thermal radiation (2007). Thermal sensors that use thermography have many uses that they were created for. Thermal sensors are used in the military to detect explosives frequently. The marines use thermography to spot enemies also. Thermography is not only used by the military, it is also used for medical reasons such as detection of breast cancer (Flir Threat Detection,

  • Ways of Transmitting Heat: Conduction, Convection and Radiation

    1201 Words  | 3 Pages

    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 ...

  • The Four Major Laws Of Thermodynamics

    1460 Words  | 3 Pages

    Thermodynamics is defined as “the study of heat transfer and its relationship to doing work.” Specifically, it is a field of physics that has to do with “the transfer of energy from one place to another or from one form to another” (Drake P.1). Heat acts as a form of energy that equates to a total amount of work. Heat was recognized as a form of energy around the year 1798. Count Rumford (Sir Benjamin Thompson), a British military engineer, observed that “numerous amounts of heat could be generated in the boring of cannon barrels” (Drake P.1), which is where a cannon’s firing port is enlarged using a drill and immense amounts of heat to make the metal malleable. He also observed that “the work done in turning a blunt boring tool was proportional

    Conduction, convection, and radiation are all types of heat transfer in which heat is transferred from a system to its surroundings. As humans, we are in the presence of, and manipulate these heat transfers all the time. Heat transfer is very important to our every day lives as we try to live in a world where the temperature outside is not comfortable and we want our food cooked. Some people go out of their way to get more radiation to get a tan, or use convection while siting in a sauna. In this paper, I will discuss the physics behind these three heat transfer methods, their equations, and some everyday examples.

  • Essay On Thermoster

    1011 Words  | 3 Pages

    Thermostats are a usual method of sensing a temperature of a system and maintain the system’s temperature at a predefined point. The most popular and ubiquitous appliance in any home is a Refrigerator. A thermostat maintains the pre-set value of temperature by switching the heat conduction. In short, it regulates the heat flow. In Physics, there is no such thing as cold, its either higher temperature or lower temperature – heat flow (absorption or dissipation). Thermostats are a regular feature in Air Conditioner, Microwave Ovens, Ironing machines, Induction Heaters and Refrigerators in home appliances category. At the same time in many scientific labs (biology, physics or chemistry research domains) storing experimental samples (veils, substrates, materials etc.) these above appliance have a larger role to play. Most of these laboratory experiments run for weeks and such appliances run almost 24x7. Maintaining the pre-set temperatures are an integral part in such labs.

  • Thermal Energy

    When we place two objects with different temperatures in contact with each other, the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while others make poor conductors of heat or excellent insulators. Silver, copper, and gold make excellent conductors of heat. Foams and plastics make good insulators of heat but make poor conductors. Last night for dinner, I made myself a grilled cheese sandwich and a bowl of tomato soup. I heated the soup faster than I cooked the sandwich so I poured the hot soup into a bowl and finished cooking the sandwich. Once I was done cooking, I gabbed the soup bowl and burned my hand. The heat from the soup made the bowl hot. This is an example of conduction.
