A copper block with a mass of 250 grams is cooled to -196°C by being immersed in liquid nitrogen. The block is then placed in a Styrofoam cup containing some water that is initially at +70.0°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 10 J/kg.
Find the MAXIMUM mass of water that could have been in the cup, if the final equilibrium temperature is 0.0°C. AND find the minimum mass of water that could have been in the cup, if the final equilibrium temperature is 0.0°C
