Refer to the temperature versus time graph (Figure 2) when answering the questions in Parts C through \( \mathrm{F} \). A system consists of \( 0.250 \) kg of water. The system, originally at \( T_{\mathrm{A}}=21.0^{\circ} \mathrm{C} \), is placed in a freezer, where energy is removed from it in the form of heat at a constant rate. The figure shows how the Learning Goal: temperature of the system takes \( t_{1}=10 \mathrm{~min}=600 \mathrm{~s} \) to drop to \( 0^{\circ} \mathrm{C} \), after which the water freezes. Once the freezing is complete, the temperature of Energy can be added to a system either by doing work \( W \) the resulting ice continues to drop, reaching temperature \( T_{\mathrm{B}} \) after an hour. The following specific heat and heat of transformation values for water may be on it or by adding heat \( Q \) to it. Energy transter by work requires a force to act through some distance. Energy transfer in the form of heat occurs between objects that are at different temperatures, with energy spontaneously traveling from the higher-temperature object to the lowertemperature one. When energy is added to an isolated system in the form of heat, either the temperature \( T \) of the system will increase or the systern will undergo a phase change at a fixed temperature. Figure Part C How much energy must be transferred out of the system as heat \( Q \) to lower its temperature to \( 0^{\circ} \mathrm{C} \) ? Express your answer numerically in joules.
