Question details

FNTs 5 and 6 emphasized the significance of the beginning and end of the interval. This FNT asks you to determine the interval (specifically the final state) using Energy-Interaction Model, given the amount of heat transferred to the system. 7) Now, imagine you are gradually adding heat to a 500g block of ice initially at -25°C. You can ignore the pots thermal energy and assume all input energy is perfectly transferred to the H2O. One question that could be asked is, What is the final state of the water (phase and temperature) after the addition of 252 kJ of heat? a) Explain why, based only on the given information and without further analysis/calculation, it is not possible to construct a single energy-system diagram that could be used to determine the final state of the water. (Hint: try to construct such a diagram. Explain why you cant.) In cases like this, you must first use the model to analyze a shorter interval. Can you construct an energy system diagram that could be used to determine how much energy is needed to increase the temperature of the ice from -25°C to 0°C? How does this energy compare to 252 kJ? Now explain how to proceed using the Energy-Interaction Model to find the final state of the H2O, when 252 kJ are added. b)
