Next Fact FOUNDATION and HIGHER Conduction is the flow of heat through materials from where they are hot to where they are colder. Most metals are good conductors of heat. Wood, glass, plastics, rubber and things like cotton and leather are bad conductors. Good conductors are bad insulators; bad conductors are good insulators. Everything conducts to some extent - Liquids and gases also conduct heat but only very slowly. Water is a very poor conductor - it takes a lot of energy to heat it up. Metal objects feel cold if you touch them because they carry heat away from your hand. Air is a terrible conductor and this is why clothes which trap air are warm - fleeces, for example. Fibre glass is also a very bad conductor and is used as 'lagging' to insulate water pipes, ovens, friges and the roofs of houses. HIGHER ONLY: Conduction and the kinetic theory Metals have a 'sea' of electrons which move at random inside them. When one part of a metal is heated, electrons there move faster and travel further. As a result they can quickly pass on their kinetic energy to cooler parts, raising the temperature. In non-metals, conduction occurs because the atoms themselves make 'colder' parts of the non-metal vibrate. There are very no free electrons to do the conduction quickly, so the process is slow.

In a qualitative manner, we can describe the temperature of an object as that which determines the sensation of warmth or coldness felt from contact with it. It is easy to demonstrate that when two objectsof the same material are placed together (physicists say when they are put in thermal contact), the object with the higher temperature cools while the cooler object becomes warmer until a point is reached after which no more change occurs, and to our senses, they feel the same. When the thermal changes have stopped, we say that the two objects (physicists define them more rigorously as systems) are in thermal equilibrium . We can then define the temperature of the system by saying that the temperature is that quantity which is the same for both systems when they are in thermal equilibrium. If we experiment further with more than two systems, we find that many systems can be brought into thermal equilibrium with each other; thermal equilibrium does not depend on the kind of object used.

86. How Much Heat Per Hour Do Humans Dissipate? of ingested energy to be different than expended energy. quite a bit, and the heat/workratio Answered by Gregory Ogin, physics Undergraduate Student, UST, St http://www.physlink.com/Education/AskExperts/ae420.cfm

Asked by: George West Answer joules ingested per day. This means that the average person expends ~8.37 x 10 joules of energy per day, since most of us are in some sort of equilibrium with our surroundings. Assuming most of this energy leaves us in the form of heat, I calculate that on average we radiate ~350,000 J of energy per hour. Since Watt is just Joules per second, this is roughly equal to energy given off by a 100 Watt light bulb! The one thing I have neglected (not being a biologist/chemist/physician/whatever) is chemical and biological changes in the human body that would cause the amount of ingested energy to be different than expended energy. This could be due to things like creation/burning of fat, abnormal heat radiation (such as when the body temperature rises while the immune system combats an illness), or increased activity (such as a weightlifter building muscle mass, although I suspect that at higher levels of activity the body's efficiency drops quite a bit, and the heat/work ratio goes up).

Contents: Cv in Bits IFZX Other Stuff Information physics: From energy to codes T his is an evolving collection of notes for educators on how the tools of thermal physics are grounded in gambling theory, and how in that context they are providing clues to more complex things going on around us than 19th century thermodynamicists might have imagined. The new tools have been guiding error-correction in communication lines and data-compression methods for half a century, but they are now moving into applications relevant not just to the future of computers. They may in fact someday provide a common physical framework for considering such disparate (and sometimes competing) issues as conservation of available work, maintenance of genetic diversity within and between species, and the future of cultural diversity in the presence of constraints imposed by increasingly rapid means of communication and transportation.

Friction slowing things down Whenever anything moves, there's usually some form of friction trying to stop it. Friction is sometimes useful, at other times it's a problem. There are two main types of friction:- "Static" or "sliding" friction This type of friction occurs when dry surfaces rub together. The frictional force depends only on:- the type of surfaces how hard the surfaces are pressed together. Friction makes this lorry difficult to move, but it does help by giving the man a good grip on the road. In this diagram, the weight of the block provides the force pressing the surfaces together. Watch the animation carefully: If this picture isn't moving, click on "Refresh"/"Reload" If we push the block harder and harder, the frictional force will increase, until it reaches a maximum (in this case, 2.5N)
