A 0.4 kilogram sample of Aluminum at 115 degrees Celsius is put into a container containing 0.5 kilograms of water at 15 degrees Celsius. Neglecting the small amount of energy absorbed by the container and knowing that the specific heat of Aluminum is 900 kJ/kg*C, and the specific heat of the water is 4186 kJ/kg*C answer the following question.
Compared to the heat liberated by the aluminum, the heat absorbed by the water is
greater.
smaller.

what heat the alumin gives off has to be equal to the heat the water gained, No you have an issue here, putting the hot aluminum into dwater, some of the water will vaporize, but if you configure the container so that no heat is lost, that steam will recondense and the heat (and water ) will not be lost.
