Se calienta una barra de hierro de 200 g y luego se coloca
en 100 g de agua en un recipiente aislado. La temperatura
del agua aumenta desde los 20°C hasta los 50°C. ¿Cuál fue
la temperatura inicial en grados Celsius de la barra de
hierro? (calores especĂficos: hierro=450 J/Kg. K - Agua
=4186 J/Kg. K). Exprese su resultado con dos decimales.
