A 32.5 g of aluminum initially at 45.8 ˚C is submerged into 105.3 g of water at 15.4 ˚C. What is the final temperature of both substances at thermal equilibrium? (Assume that the aluminum and the water are thermally isolated from everything else). (NOTE: The specific heat for water is 4.184 J.g-1 ˚C-1 and that of aluminum (Al) is 0.903 J.g-1 ˚C-1 )
