En una cubeta hay agua que se encuentra a temperatura ambiente (Ta= 20°C). En ella se deposita un yunque de hierro de 25 kg que se encuentra a 320°C. Luego de un breve momento, el pedazo de metal es extraído de la cubeta, donde se le mide, por medio de un termómetro digital la temperatura nuevamente, resultado marcar 60°C. Considerando que el calor especifico del hierro es de 448 [J/Kg°C] Determine: a) Que material absorbe calor (1p) R/:
b) Que material cede calor (1p)
c) Temperatura de equilibrio térmico (2p)
d) Método de transferencia que predomina (2p)
e) Cantidad de energía que está fluyendo [Q] (6p: 2p identificar, 2p relacionar y 2p resolver
