Refer to the temperature versus time graph (Figure 1) when answering the questions. A system consists of 0.250kg of water. The system, originally at T_(A)=21.0^(@)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 temperature of the system takes t_(1)=10min=600s to drop to 0^(@)C, after which the water freezes. Once the freezing is complete, the temperature of the resulting ice continues to drop, reaching temperature T_(B) after an hour. The following specific heat and heat of transformation values for water may be helpful. specific heat of ice (at0^(@)C) c_(i)=2100J//(kg*K) heat of fusion (ice to water phase change at {:0^(@)C) L_(f)=3.34 xx10^(5)J//kg specific heat of
Refer to the temperature versus time graph (Figure 1) when answering the questions. A system consists of 0.250kg of water. The system, originally at TA=21.0∘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 temperature of the system takes t1=10min=600s to drop to 0∘C, after which the water freezes. Once the freezing is complete, the temperature of the resulting ice continues to drop, reaching temperature TB after an hour. The following specific heat and heat of transformation values for water may be helpful. Part A How much energy must be transferred out of the system as heat Q to lower its temperature to 0∘C ? Express your answer numerically in joules. View Available Hint(s)
