An 65.73 g sample of aluminum is placed on a 56.35 g sample of copper initially at 111.86oC. If the heat is only transferred between the metals (with no loss to the surroundings) and the final temperature of both metals is 36.38oC, what is the inital temperature (in oC) of aluminum?
Heat lose of Cu = Heat gain of Al
mcT = mcT
56.35*0.385*(111.86-36.38) = 65.73*0.902*(36.38-t)
t = 8.370C
The initial temperature of Al = 8.370C
