An iron bar at 200 degrees celcius is placed in thermal contact with an identical iron bar at 120 degess celcius in an isolated system. After 30 minutes, both iron bars are at 160 degrees celcius. if iron bars were placed in thermal contact in an open system instead of an isolated system, how would the results be different? Assume that the room temperature is 25 degrees celcius.

o conteúdo de calor de um sistema é igual à entalpia apenas para um sistema que é constante

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
