A 1040kg iron bar with a length of 2.00m and temperature of −45.25˚C is immersed in 50kg of liquid water at 90˚C. The specific heat of liquid water 4.186 kJ/(kg˚C), and the latent heat of fusion of water is 333kJ/kg. The specific heat of iron is 0.45kJ/(kg˚C) and its melting point is 1538˚C. The goal is to determine the final temperature of the system (iron+water) once it reaches thermal equilibrium, and also the state of each substance (solid, liquid, gas)   a) What is the final state of the iron (solid, liquid, gas)? Why? b) Calculate the amount of heat lost by the liquid water in cooling to 0˚C as a liquid c) Assuming all the heat in (b) goes into the iron, what is its T at thi
