A cup of newly brewed 330 g cofee is to hot to drink when served at 88 degree celcisus.

a) IF you add 60 g of ice at -15 degree celsisus to it. What is the final termpetate Tf of the cofee when it reaches thermal equilibrium?

b) What is the mass of the ice cube needed in order to cool the coffee to a pleasant 50 degree celsisus? assusming specific heat of coffee is 4190 J/kg * C and the specific heat of ice is 2050 J/kg * C. The latent heat of fusion is Lf= 334 x 10^3 J/kg and the latent heat of vaporization of water is Lv= 2.26 x 10^6 J/kg
