A 29 g ice cube at 0.0°C is added to 110 g of water in a 62 g iron cup. The cup and the water have an initial temperature of 25°C.

(a) Find the equilibrium temperature of the cup and its contents.

i don't understand how the iron cup changes the situation. please help.

    The specific heat of iron is 0.449 J/g K.
    It will provide some of the heat needed to melt the ice. The temperature drop of the mixture will be less because the iron is there.
