You hold a 50 g sphere of copper [cp= 0.4 J/(g . C) ] in one hand and a 25 g sphere of aluminum [cp= 0.9 J/(g . C) ] in the other hand.If both absorb energy at the same rate, which will come to your body temperature first and why?
A) copper, because the mass is larger
B) aluminum, because the specific heat is larger
C) aluminum, because the mass is smaller
D) copper, because the heat capacity is smaller
E) Both reach body temperature at the same time because they absorb energy at the same rate.
