An Overview of the First Law of Thermodynamics (1000 words, 6 pages)

AbstractThe first law of Thermodynamics states that during the heat exchange in an isolated system, heat is neither created nor destroyed. In the first experiment we did three trials to determine the heat capacity of the calorimeter which came out to be 22.15, 17.93 and 22.15 with an average of ... Read More

A Discussion About the First and Second Law of Thermodynamics (585 words, 2 pages)

Thermodynamic deals with the transformation of heat into mechanical energy. The first law of thermodynamics states that a change in internal energy is equal to the heat added to the system minus the work done by the system, UQ-W. If heat is removed Q is negative because we are taking ... Read More

An Analysis of the Second Law of Thermodynamics and Its Use (1437 words, 3 pages)

AbstractThe purpose in experimenting with computer simulations was to compare oxygen consumption rates in different mammalian subclasses. We compared monotremes, marsupials, and placental mammals at both warm and cold temperatures. The results supported our hypothesis that when temperature increased, metabolic rate decreased. This was also supported using a students t-test. ... Read More

An Analysis of the First Law of Thermodynamics (4905 words, 18 pages)

I. Opening Comments (Chapter 3) A. Life creates order out of disorder through a never-ending series of chemical reactions B. This is Metabolism and the ability to Metabolize C. Most of the chemical reactions required by the cell would not occur at physiological conditions D. Control of these reactions is ... Read More

An Analysis of the Concept Behind the Second Law of Thermodynamics (462 words, 1 pages)

The second law of thermodynamics states that energy transitions are imperfect. No matter what, energy is lost. In machines an 75 loss of energy is considered average. In biological reactions there is usually a 60 loss. Since all reactions are constantly losing a percentage of the energy they give, it ... Read More

The Case of the Second Law of Thermodynamics (751 words, 3 pages)

The Second Law of ThermodynamicsThe Second Law of Thermodynamics has several variations. One version says thatsome heat is always wasted when converting heat into mechanical energy. In other wordsall heat can not be completely converted into mechanical energy. Another states that heatnormally flows from high to low temperatures. So why ... Read More

The Second Law of Thermodynamics vs. the Theory of Evolution (258 words, 1 pages)

Second Law of Thermodynamics vs. EvolutionAccording to the second law of thermodynamics, when energy is converted from one form to another, the amount of useful energy decreases. In relation to the theory of evolution, this law is not contradictory. The second law of thermodynamics is not relating to energy within ... Read More

Understanding the Concept of the First Law of Thermodynamics (795 words, 3 pages)

chat.onload(function(chats, online) var link ("content1chatid") link.onclick function(e) chat.openrandom(0) return false ) chat.onupdate(function(chats, online) )The first law of thermodynamics states that energy can be converted from one form to another through a change in phases but cannot be created or destroyed. This law is thus based on the basic principle governed ... Read More
