iron block of unknown mass at 85oC is dropped into an insulated tank that contains 100L of water at 20oC. At the same time, a paddle wheel driven by a 200W motor is activated to stir the water. It is observed that thermal equilibrium is established after 20min with a final temperature of 24oC. Assuming that the container is perfectly insulated, determine the mass of the iron block (kg). Use C of IRON= 0.44 kJ/kg-K. draw a figure also, and explain each step by step solution.

Chemical and Phase Equilibrium

Phase diagrams or equilibrium phase diagrams are the graphical representations that show the phase transformations of the constituting elements with respect to the pressure, temperature, and compositions. The diagrams show the conditions that limit the different phases, namely solid, liquid, and gas. The diagram can also be utilized to verify the relations between the state variables. Most of the phase diagrams are temperature-pressure phase diagrams, with the variable parameter as the composition. Usually other variables such as solubility and pressure parameters are not indicated in the phase diagram. For a one-component system (unary phase diagram), the phase diagram is generally a function of temperature and pressure as the state variables, or temperature and volume. However, for a binary system (two-phase) having two components, the phase diagram is a function of temperature and composition as the state variables only. Coexisting of the different phases of the constituting elements is indicated in the phase diagram. A ternary phase diagram can be characterized by consisting of three phases in equilibrium.
