The Physics Of Thermal Energy - 1609 Words

Thermal Energy in Peanuts Kristin Guenev, Hannah Potter, Rebecca Fluegel At the ignition of a peanut, how much thermal energy is produced? The same energy that is emitted at the burning of a single peanut contains the same principles that heat our homes, cook our food, or why we feel cold in the winter and warm in the summer. Though much associated with temperature, thermal energy is not the same. If we were dealing with temperature in our experiment, we would have asked: What is the change in temperature of water when a peanut is burned? However, thermal energy is the potential movement of heat from one object of high temperature to lower temperature. When comparing a steaming cup of coffee, and an iceberg, the temperatures are exactly what they seem to be, but the thermal energy of the two objects are the direct opposite of what they are assumed. Sure, the coffee has more heat, but the iceberg has more energy. One of the reasons we chose a peanut, of all things, was the remarkable amount of thermal energy that it contains. Due to our experiment and the specific heat equation, Q = mcDT, where â€Å"Q† is the heat flow in calories, â€Å"m† is mass, â€Å"c† is the specific heat and â€Å"DT† is the temperature difference between the two objects, we discovered that an average peanut can produce 45.54 calories, or 190.5 joules, which will further be explained. This conclusion of a single peanut’s potential energy was what attracted our group to theShow MoreRelatedThe Theory Of Heat : The Natural Sciences Span Over A Wide Range Of Phenomena1126 Words   |  5 Pagesallowed to research these phenomena due to underlying connections between subtopics. In physics one can view many underlying connections between different subtopics. For example; in thermodynamics. Thermodynamics is a branch of physical science that deals with the relations between heat and other forms of energy such as mechanical, electrical or chemical energy. More importantly, heat itself and its relation to energy and work done on a system. Many people have misconceptions about heat.

To contribute towards acceleration of this transition to humanity is the primary guiding rationality behind my desire to pursue higher education in engineering.

It literally controls how our reality operates and how our existence came to be in this universe, it actually it what made our universe. When you think about physics you probably think about friction and forces but it is a much broader idea. Physics is what controls how the atoms that make up everything work with each other to formRead MoreHow The Shape Of Ice Affect How Fast It Melts?1254 Words   |  6 Pageswater that has a temperature of any degree above thirty-two degrees Fahrenheit. Before water technically becomes water, which is the name of the liquid state, it starts as a gas called water vapor. After water vapor condenses because of a loss of energy, it is then in liquid phase of H2O, called water, which can then be broken down in the smallest unit; atoms. Professor John Blamire of brooklyn.cuny.edu describes a single water molecule, the smallest part of a chemical element or compound thatRead MoreThe Between Heat And Energy893 Words   |  4 Pages The term thermodynamics is known as the branch of physics that covers the relationship between heat or temperature and all the forms of energy, including mechanical, electrical, or chemical. Thermodynamics is a combination of four laws, which are known as zeroth law of thermodynamics, first law of thermodynamics, second law of thermodynamics, and third law of thermodynamics. According to Wolfram, The relation between heat and energy was important for the development of steam engines, and in 1824Read MoreA Discussion On My Internal Assessment1555 Words   |  7 Pageselectricity. We can witness its innumerable uses in our lives on a day-to-day basis, so electricity, particularly its relationship with heat, was always a subject that I found incredibly fascinating. I remember first learnin g about the topic in my IB Physics course just the past year and regretting that we couldn t delve deeper into the topic or see the phenomenon in person through any lab work. This is precisely why I decided to take this particular topic as the premise of my internal assessment.

Once the stress inside the crust grows beyond the strength for that location of the crust, a failure occurs within the crust and seismic waves, which we know as earthquakes, are radiated outward. It was once thought that this description of seismic activity was the cause for all earthquakes, but now seismologists know the way earthquakes form and start is a very diverse process.Read MoreWhat Does Thermodynamics Affect The World?1458 Words   |  6 PagesLaws of Physics, takes a look at the big picture of physical motion and how it effects the world around us. â€Å"Thermodynamics is a branch of physics which deals with the energy and work of a system.† Without the knowledge of thermodynamics, everyday life would be much different.
