3. Una barra de acero de 500 g se está forjando para una herramienta. En el proceso se calienta a 1000 °C y se enfría rápidamente en 2 kg de aceite térmico a 20°C para su templado. Si consideramos que el acero es básicamente hierro (>95%) con una capacidad calorífica de 0.444 J/(g K) y sabemos que el aceite térmico tiene una capacidad calorífica de 5.80 J/(g K). Cuál es la temperatura final en equilibrio
