A 32.5g cube of aluminum initially at 45.8 C is submerged into 105.3g water at 15.4 C. What is the final temp of both substances at thermal equilibrium. Assume the al and the H2O are thermally isolated from everything else)Specific heat cap Al= .903Specific heat cap H2O= 4.18I understand this problem but In my math i get to:(DeltaT) Al = -14.998 X (DeltaT) H2OAnd im lost. Anyone able to explain the completion of the problem? Any help is greatly appreciated
