What mass of water at 22.0 °C must be allowed to come to thermal equilibrium with a 1.66-kg cube of aluminum initially at 1.50 multiplied by 102 °C to lower the temperature of the aluminum to 57.1 °C? Assume any water turned to stream subsequently recondenses.

Answer 1

Recheck the initial temperature of the aluminum. It is probably 1.50*10^2 (or 150) degrees, not 1.50 multiplied by 102.

Set the heat loss from the aluminum equal to the heat gained by the water, and slve fr the mass of water. You will need to know the aluminum specific heat.
