A copper block with a mass of 300 grams is cooled to 77K by being immersed in liquid nitrogen. The block is then placed in a Styrofoam cup containing some water that is initially at + 50.0°C. Assume no heat is transferred to the cup or the surroundings. The specific heat of liquid water is 4186 J / (kg °C), of solid water is 2060 J / (kg °C), and of copper is 385 J / (kg °C). The latent heat of fusion of water is 3.35 x 105 J/kg. When the system comes to equilibrium, the temperature is 0°C. (a) Calculate the maximum possible mass of water that could be in the cup. (g) (b) Calculate the minimum possible mass of water that could be in the cup. (g)
