Ideal systems X real systems To treat this issue, consider the flow of heat (thermal energy) body with a higher temperature to a body of lower temperature. This could be a clothes iron and a cotton shirt (System 1), or you and the air around the system (2). Systems such as those mentioned are called "real systems" and are difficult to study because they involve many factors. For example, the body and the air that surrounds it, other objects such as clothes, or even other individuals receiving or supplying heat in the same environment. It is necessary to consider that different substances exchange heat in different ways depending on the material of which they consist. The systems are ideal models of events that could happen without that manifest many factors, as in the case of real systems. With these models are made simulations trying to facilitate the understanding of the phenomenon, through some control over the factors that influence its observation. Like a musical show, you want to accurately observe only the guitarist strumming on the strings. If you could, would remove the sound and dry ice mist surrounding them and thus would be exercising control over the factors that affect their perception. Thus, would select what is important, art as guitarist maneuver the ropes. This would be his idealized system created to study the strumming of the guitar. In science, sometimes said to have created systems ideal for observing the behavior of certain quantities, seeking approaches to what is observed in real models. To speak in thermal equilibrium, we will also consider an idealized system that, in the case of this study, is called "isolated system". We will build, then our system isolated? Imagine two blocks, block A and B with different temperatures. Let's suppose that is both greater and the temperature is less than are within a box of a material which does not allow heat exchange with the external environment, or is a perfect insulator. This is our isolated system. Does that box there? Assuming that box there, let's analyze the thermal processes that take place within it? As our system is isolated within the box, there is only the passage of heat from one block to another. But how is this passage? There are two situations: the passage by conduction and radiation. In the case of conduction, the body of higher temperature (A)-trans

Idealno sustavi X stvarni sustavi Za liječenje ovog problema, razmislite protok topline (toplinske energije) tijelo s visokom temperaturom na tijelo niže temperature. To bi mogao biti odjeća željeza i pamučna majica (Sustav 1), ili ste i zrak oko sustava (2). Sustavi poput onih koje spominje se zove "pravi" sustav i teško učiti jer se radi o mnogo faktora. Na primjer, tijelo i zrak koji ga okružuje, ostali predmeti poput odjeće, pa čak i drugih osoba koje primaju ili dobavu topline u istom okruženju. Potrebno je uzeti u obzir da se različite tvari razmjenu topline na različite načine, ovisno o materijalu od kojih se sastoje. Sustavi su idealni modeli događaja koji bi se mogli dogoditi bez koje mi se mnogim čimbenicima, kao u slučaju realnih sustava. S tim modelima su simulacije pokušavaju olakšati razumijevanje fenomena, kroz neku kontrolu nad čimbenicima koji utječu na njegovu primjedbu. Kao glazbeni show, želite točno promatrati samo gitarist na drndanje žice. Ako bi, bi uklonili zvuka i suhi led magla ih okružuje, a time će biti vježbanje kontrolu nad čimbenicima koji utječu na njihovu percepciju. Tako će odabrati ono što je važno, umjetnost kao gitarist manevar užad. To će biti njegov idealizirani sustav stvoren za proučavanje drndanje na gitari. U znanosti, ponekad je rekao da su izgradili sustave idealne za promatranje ponašanja određenih količina, traži pristupe ono što se promatra u stvarnim modelima. Govoriti u toplinskoj ravnoteži, što će također razmotriti idealizirani sustav koji, u slučaju ove studije, zove se "izolirani sustav". Mi ćemo graditi, a zatim naš sustav izoliran? Zamislite dva bloka, blok A i B sa različitim temperaturama. Pretpostavimo da je i veći, a temperatura je manje nego što je unutar okvira od materijala koji ne dopušta izmjenu topline s vanjskog okruženja, ili je savršen izolator. Ovo je naš izolirani sustav. Znači li to da postoji box? Uz pretpostavku da je okvir postoji, neka se analiziraju termalne procese koji se odvijaju unutar njega? Kao što je naš sustav je izoliran u kutiji, postoji samo prolaz topline iz jednog u drugi blok. Ali kako je ovaj odlomak? Postoje dvije situacije: Prolaz kondukcijom i zračenja. U slučaju provođenja, tijelo više temperature ()-trans
