A15.7 g aluminum block is warmed to 53.6 ∘c and plunged into an insulated beaker containing 32.1 g of water initially at 24.2 ∘c. the aluminum and the water are allowed to come to thermal equilibrium. assuming that no heat is lost, what is the final temperature of the water and aluminum?

27.055 (°C)

Explanation:

the final temperature of the water and the aluminium has the same value: the aluminium block lost the heat, the water 'takes' the heat.

All the details are in the attached picture, the answer is marked with green.
