To answer the most obvious question, what is ΔHºrxn·? Well, ΔHºrxn· means the change in enthalpy. To break it down further, enthalpy is the measure of the amount of energy in a system. Every single reaction in the entire universe has a change in enthalpy. Energy is held in each and every single bond that puts together the world we see and live in today. When a reaction takes place and bonds are broken and reconnected, energy has been transferred, and enthalpy tells us how much. It is just about nearly impossible to measure all of the energy that there is out there, but scientists can measure how much energy has been transferred through the system. It would be like trying to measure the volume of the ocean, pretty much impossible, huh? But, …show more content…
It is very useful especially when comparing different fuels and substances to see which ones release more energy when they are burned. This can be helpful in knowing, especially with all of the new vehicles and machinery being built, maybe they will find a better fuel through this method. When the fuel is burned, the temperature change is measured. They then simply take the amount of fuel that was burned and compare it to the change in temperature to calculate the enthalpy change for the reaction.6. Also, many fuels produce a higher heat then others, so obviously the higher heat producing fuel yields more products. More products means a better product for the dollar which is better economically for everyone.
Looking into the present day and the future, bond enthalpies will play a big role in the scientific world. Breaking bonds between two atoms that have a strong attractive force requires a deal of energy. Which is also why it is an endothermic process, and is true for the opposite in that making a new bond between atoms is an exothermic process.6. Understanding the energy required to break each of these bonds may someday lead to much more conservative ways of going about

- Thermodynamics: The Transfer Of Heat And The Convectionexplanatory essayThermodynamic equilibrium leads to the large-scale definition of temperature, as opposed to the small-scale definition related to the kinetic energy of the molecules. The first law of thermodynamics relates the various forms of kinetic and potential energy in a system to the work which a system can do and to the transfer of heat. This law is sometimes taken as a definition internal energy, and introduces an extra state variable, enthalpy. The first law of thermodynamics allows for many possible states of a system to exist. But experience indicates that only certain states occur. This leads to the second law of thermodynamics and contrast between another state variable called entropy. The second law stipulates that the total entropy of a system plus its environment can not decrease; it can remain constant for a reversible process but must always increase for an irreversible process. Thermal energy is the energy a substance or system has due to its temperature, i.e., the energy of moving or vibrating molecule. Thermodynamics involves measuring this energy, which can "exceedingly complicated," according to David McKee, a professor of physics at Missouri Southern State University. "The systems that we study in thermodynamics … consist of very large numbers of atoms or molecules interacting in complicated ways. But, if these systems meet the right criteria, which we call equilibrium, discovered with a very small number of measurements or

However, this field is still in an early state of exploration. Experiments, including the one that is being performed at Oxford University, are just beginning to test these predictions. “A flurry of attempts has been made to calculate how thermodynamics and the quantum theory might combine” (Merali P. 1). However, quantum physicist Peter Hänggi stated that “there is far too much theory and not enough experiment” (Merali P.1) in this field of study, which is why its credibility is undermined.

They are caused when cool river water are drawn from the water source, run through a power plant, and then discharged back into the same source. This now heated water causes all kinds of mischief and damages to the health of the organisms in the aquatic environment and the environment itself. In an experiment, Gisela Lannig and Inna Sokolova of the University of North Carolina in Charlotte incubated oysters at one of three temperatures, 20°C, 24°C, and 28°C. The differing temperatures of the environment each group of oysters are exposed to in the incubator simulate thermal pollution in the oysters’ natural habitat. What they found was that "the rate of oxygen use, which can be an indicator of physical stress, was three times as high in oysters kept at the warmest temperature as it was in those kept at the coolest" (Raloff, 2005). This reveals that their environment could stress aquatic organisms with just a minute change in the temperature of the ecosystem. This stress could cause the health of an organism to deteriorate or even possibly death.

In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
