Essentially, energy is heat and heat is energy. An example of this is metabolism in humans. Humans consume food which is converted through metabolic processes, specifically glycolysis, into the energy molecule ATP (adenosine troposphere). These ATP molecules are then used for energy by being converted to ADP (adenosine diphosphate), by losing a phosphate group. This is fundamentally how humans gain energy for life functions like maintaining core body temperature. This is an example of neither created or destroyed energy, but changing one form of energy into another. Most mammals achieve energy for heat in this way.
It is important to mention that most external and environmental conditions are not suitable to be the same internal conditions of most organisms. For example, humans must sustain a normal body temperature of about 98.6 degrees Fahrenheit in order to survive. Only small fluctuations to this are within the allowable limits of biological survival. In fact, it is important to mention that the only time any organism reaches a state of equilibrium with its external environment in temperature and pressure is when the organism has died (Recordati et al, p. 27). Considering that humans require a body temperature of 98.6 degrees Fahrenheit, most weather conditions on the planet are much different than this temperature. For example, individuals living in arctic climates may never experience outside temperatures of anywhere near 98.6 degrees. Core temperature is homeostatically maintained and behaviorally maintained. We wear coats and warm clothing in colder weather to conserve body heat. We wear less clothing in warm climates and weather conditions to keep body temperature from elevating too much. ...Download file to see next pagesRead More

... proxy records (Kuijpers 2009, p.23). Due to wide variety of climatic regimes, the pas information would be restricted to the tropical plains of the site. The historical information was the most important original source of the palaeoclimate study due to the quality of quantification and interpretation. To provide distinction between the different degrees of fleet, snow and frost in the tropical plains of South China, development of cold winter index was enhanced (Kaufmann 2003, p.204). The cultivation of perennial herb and citrus trees in china from the records collected clearly shows the existence of medieval warm period in other parts of the word other than the Europe. The citrus tree and perennial herb were used in the twelfth, eighth...

Impacts of ocean acidification on the wider marine community (Cat) Some organisms seem to be healthier than others, in relation to our changing seas and ocean tides, emphasizing the issues in establishing the extent to which the flora and fauna would be affected. After assessing an Antarctic species of krill, Kawaguchi, et al. (2011), determined that both geographical location and migrations (both localized and over long distance) must be included in evaluating species. Furthermore, OA is not meant to manifest in the same manner in all parts of the world (Doney, et al., 2009). Some areas may be more vulnerable and may go through fast-paced changes in chemistry, more so than others. This may be seen in cold waters...

Thermodynamics

...Insulated Pizza Delivery Bags Thermodynamics, the study of energy and its transformations, has a set of four laws that govern the behavior of energy.Scientists have theorized that energy can be exchanged between physical systems as heat or work. They also put forward the existence of a quantity named entropy which can be defined as an isolated system that is in thermodynamic equilibrium. On the microscopic and subatomic level an isolated system as insulated pizza bags contains particles whose motion defines its properties, The first law of thermodynamics: 'The internal energy of an isolated system is constant.' Therefore the internal energy of the content of the pizza bag remains constant according to the first law of thermodynamics...

...Experiment on Linear Heat Conduction INTRODUCTION Heat Transfer is the phenomenon of exchange of thermal energy from one physical system to another.Heat transfer takes place via three mechanisms viz. Conduction, Convection and Radiation. Conduction takes place by the transfer of heat energy between stationary particles adjacent to each other. Convection takes place by the transfer of heat energy by the flowing matter and as such is observed in fluids (liquids and gases). Radiation or Thermal Radiation is the process of transfer of heat through radiation or electromagnetic waves and is independent of medium. It is a common observation that when a hot body is brought in contact with a cold body, transfer of heat takes place from the hot body...

(ISOBARIC) (ISOCHORIC) (ISENTROPIC, POLYTROPIC, & ISOTHERMAL) (b) Why are some of these processes not achievable in real life? Some of these thermodynamic processes are not achievable because not all quasistatic processes can be reversed in real life. As such, a gas that is infinitesimally being compressed in a piston-cylinder setup with friction takes an irreversible path. Q1.2b Polytropic expansion takes place in an engine cylinder. At the beginning of expansion, the pressure...

Ebola Ebola is a viral disease caused by Ebola virus. This virus causes viral hemorrhagic fever (VHF) (W.H.O. 12). This fever is extremely severe in humans, whenever it attacks. This viral hemorrhagic fever is known to have up to 90% fatality rate. The fever is common in West Africa and central Africa. These places are near the tropical forests. The Ebola virus can be transmitted from wild animals to human beings. It can also be transmitted from human to human. Fruit bats (pteropodidae family) are the natural hosts of this deadly virus (W.H.O. 12). At the moment, there is no known vaccine or treatment for viral hemorrhagic fever and Ebola virus. This applies to both humans and animals.
The first case of Ebola occurred in 1976...

Thermodynamics

work (W) is made of electrical work (We,in), paddle-wheel work (Wpw,in), and boundary work (Wb) and for a piston – cylinder setup with insulation, ‘Q’ zeroes out (since there would be ‘no heat transfer’ between the system and its surroundings).
Hot exhaust gases of an internal combustion engine are to be used to produce saturated water vapour at 2 MPa pressure. The exhaust gases enter the heat exchanger at 400C at a rate of 32 kg/min while water enters at 15C. The heat exchanger is not well insulated, and it is estimated that 10% of heat given up by the exhaust gases is lost to the surroundings. If the mass flow rate of the exhaust is 15 times that of water, determine:
An air-conditioning system involves the mixing of...

Environmentalists are working round the clock to establish ways and means to curb the causes of this global phenomenon. One such way is the rules and policies that have been documented and branded by the US’ Environmental Protection Agency as a significant channel to combat global warming. Accordingly, the rules and policies are supposed to be adopted by the world and will regulate activities in the coal industries. This is because the industry has been marked as a major source of carbon dioxide. The agency is doing a very good job in conserving the environment. It is agreeable that global warming is an impending...
