En un experimento de calorimetría, 0.50 kg de un metal a 100°C se añaden a 0.50 kg de agua a 20°C en un vaso de calorímetro de aluminio, cuya masa es de 0.250 kg. A) Si un poco de agua salpica y sale del vaso al agregar el metal, el calor específico medido será 1) mayor, 2) igual o 3) menor que el valor calculado para el caso en que no se salpique agua. ¿Por qué? B) Si la temperatura final de la mezcla es de 25°C, y no se salpica agua, ¿qué calor específico tendrá el metal?
