Assuming that no intensity is lost, what accomplish the last sphere be when a 15.0 g fragment of silicon at 95.0°C is placed in 50.0 g of infiltrate at 20.0°C? The specific intensity ability of silicon is 0.169 cal/g°C.
intensity lost by silicon = intensity gained by infiltrate
msilicon*Ssilicon*DT = mwater*Swater*DT
15*0.169*(95-x) = 50*1*(x-20)
x = last sphere of silicon,infiltrate structure = 23.62 C
