The Thermos and Thermodynamics Physics around Campus Phoebe Seaver Physics 102 Spring 2017 In the photo, we see two coffee cups, one that is in an insulated thermos with a lid, and one that is a regular mug open to the air, on a college student’s desk at home during their finals studying. It is well known that as coffee sits in any container, it cools down towards room temperature, making it less tasty to drink once it gets lukewarm or even room temperature. However, if it is too hot, it can burn the drinkers tongue and throat, which is incredibly painful, speaking from experience. The rate at which coffee cools may not seem like a science, but in fact, this plays into the laws of thermodynamics that are present in†¦show more content†¦Often, energy is lost to the surroundings, and not directly transferred from one object to the other. However, a perfect thermos would prevent any heat from leaking out or in. Energy in the form of heat can flow between materials inside the thermos to the extent that they have different temperatures; for example, between ice cubes and warm coffee. The transfer of energy continues until a common temperature is reached at thermal equilibrium (Cutnell 2014). Thermal equilibrium occurs when there is no heat flow between two materials, making them essentially the same temperature. This is why the coffee continues to cool down the longer it is exposed to the air, because heat exchange is occurring, and the liquid is cooling down from its original warmth to be more like the room that is it in, as the room has less heat. This is why a thermos causes the coffee to cool down slower, because the thermos provides insulation against the exchange of heat from the outside. The extra insulating layer is actually a vacuum, or absence of air, formed during the construction of the thermos. The best insulator possible is a vacuum, because there s no air. If there s no air to transfer heat, then the heat is retained where it is (wonderopolis.org). The equation for Specific Heat: .

Now we will discuss a brief history of early atomic battery development. Henry G. J. Moseley, known for developing the Atomic Number and numerous other contributions to physics and chemistry, created the first known atomic battery in 1913 with his demonstration of the beta cell. He experimented with a radioactive isotope of the element radium, and the respective emissions of beta particles, to form the first atomic batteryRead MorePurpose For A Career In Engineering1025 Words   |  5 Pageshigh school, deeply intrigued by mechanisms and experiments in physics, I frequently took part in the State Science Exhibitions demonstrating models from solar oven to spring-mass systems.

Some terms involved with these particular concepts include: closed system, empirical law, free energy, joule’s law, specific, temperature, and thermodynamics. The general defined term of convection is â€Å"the heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it† (Georgia State University). â€Å"In the world of physics, theRead MoreTaking a Look at Heat Transplantation1530 Words   |  6 Pagesto learn the real meanings of those terms and how the heat is transferred from a place to place, and understand the real context of those terms in everyday life. Everyone has felt heat, but what is it? The simple answer is that heat is energy. In physics heat is identified as a source of energy and can be observed only when it is transferring from a one place to another. All matter in the universe, is made up of molecules and atoms. These atoms are always in different types of motion and this motionRead MoreEssay on Tom Stoppards Arcadia2125 Words   |  9 Pages Tom Stoppard parallels the Second Law of Thermodynamics with the human experience in his play Arcadia. The parallelism suggests truths about the evolution of science and human society, love and sexual relationships, and the physical world. The Second Law drives the formation of more complex molecular structures in our universe, the diffusion of energy, such as heat, and is inhibited by the initial energy required to unlock potential energies of compounds. Stoppard takes these concepts and exploresRead MoreThe Effect Of Temperature On Human Body2068 Words   |  9 PagesThermodynamics as a field has many applications- everything from calculating the efficiency of an engine, determining the partial pressures of gas in a reaction to calculating the amount of energy required for a reaction to occur. These fore mentioned calculations can be used to do the same for the human body. The natural processes of the human body revolve around energy. Each system within the body contributes to the energetics of the human body; the digestive system converts food to energy thatRead MoreMotivation Letter And Research Objectives Essay1506 Words   |  7 Pagesstrategies adopted earlier in life helped me succeed not only to prepare myself for the exam, but also provided an opportunity to start teaching English language, mathematics and physics in a private educational institute.

This idea, however, violates the First Law of Thermodynamics, which states that matter cannot be created nor destroyed (Strickland, 2008). The continuing formation of stars and galaxies also goes against scientific thinking that can be found in the Second Law of Thermodynamics. This law of entropy suggests that systems of change become less organized over time, which is not the theory presented by scientists concerningRead MoreDesign Of An Integrated Circuit9821 Words   |  40 Pagesactive, were placed over a piece of semi-conductive material ( Germanium piece) that was half the size of a paper clip.
