In physics, thermodynamics (from the Greek θέρμη therme, meaning "heat" and δύναμις, dynamis, meaning "power") is the study of energy conversion between heat and mechanical work, and subsequently the macroscopic variables such as temperature, volume and pressure. Its progenitor, based on statistical predictions of the collective motion of particles from their microscopic behavior, is the field of statistical thermodynamics (or statistical mechanics), a branch of statistical physics. Historically, thermodynamics developed out of need to increase the efficiency of early steam engines. Typical thermodynamic system, showing input from a heat source (boiler) on the left and output to a heat sink (condenser) on the right. Work is extracted, in this case by a series of pistons.From Wikipedia under the

Someone posted something about cleaning your room violating the 2nd law of thermodynamics... and that just blew my mind, but the only thing is... I have no idea how it does violate it... can some please enunciate? Asked by Ryan C - Mon Aug 25 19:08:40 2008 - - 6 Answers - 0 Comments A. The so-called "natural order of things" is to increase in entropy. It's the old "the entropy of the universe is increasing" thing. Cleaning your room decreases the entropy of your room which is the opposite of the "natural order of things". But of course the energy conversions required for your body to go through the motions of cleaning your room will produce an overall increase in the entropy of the universe. Therefore there is no violation of the second law. Answered by pisgahchemist - Mon Aug 25 19:13:08 2008 how do the first two laws of thermodynamics relate to heat engines? Q. I have heard that the first two laws of thermodynamics relate to heat engines. I am doing a small powerpoint of thermodynamics but i want some way to relate it to heat engines. Asked by C-raig - Mon Mar 16 22:46:45 2009 - - 1 Answers - 0 Comments A. Heat Engine after all is a energy processing unit which gives you some useful work required to move things against some forces at the cost of so called internal energy of some systems. First law is just the statement of law of conservation of energy. It is extension of law of conservation of Mechanical energy of bulk particles. Mechanical energy includes the kinetic energy and the potential energy. It is found that this is not conserved and energy seems to disappear somewhere. With experiemntal and theoretical considerations it was found that it goes into the internal energy of a system which is made up of a large number of particles at the microscopic level. Popularly it is known as heat. But internal energy is the corrcet techincal term.

Q. Cogeneration" is a term used to describe systems in which waste heat from electric generating plants is used to heat nearby homes. Such systems achieve efficiencies much greater than 50 %. Does cogeneration violate the second law of thermodynamics? 1. No, but it violates the first law of thermodynamics. 2. No, the second law only forbids efficiency equal to 100 %. 3. Yes, the second law forbids high efficiency. 4. Yes, waste heat can't be converted into mechanical work. Asked by XzoeyX - Mon May 5 00:02:59 2008 - - 2 Answers - 0 Comments A. 2 is best, but not quite right. 2nd law forbids >100% efficiency. For example superconductors can be 100%. The others are basically false. On 4, this waste heat can't be converted economically, but it could be done if you wanted. Answered by wingstwo - Mon May 5 02:21:22 2008 From Yahoo Answer Search: "Thermodynamics" Thermodynamics is a branch of physics that studies the movement of energy and how energy instills movement. More precisely, it studies the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic scale by analyzing the collective motion of their particles using statistics. 19th century physicists defined three Laws of thermodynamics to sum up the basic principles of the subject; in the 20th century, an unofficial "zeroth law" was added.
