Given 400.0 g of hot tea at $80.0^{\circ} \mathrm{C}$ , what mass of ice at $0^{\circ} \mathrm{C}$ must be added to obtain iced tea at $10.0^{\circ} \mathrm{C} ?$ The specific heat of the tea is $4.18 \mathrm{J} /\left(\mathrm{g} \cdot^{\circ} \mathrm{C}\right),$ and $\Delta H_{\text { fusion }}$ for ice is $+6.01 \mathrm{kJ} / \mathrm{mol} .$

Key Concepts

Latent Heat of Fusion

Latent heat of fusion is the amount of energy required to change a unit mass of a substance from its solid phase to its liquid phase at its melting point, without a change in temperature. This concept is critical in situations where a phase change occurs, such as melting ice, and must be considered in the overall energy balance when mixing substances of different states.

Specific Heat Capacity

Specific heat capacity is a material property that defines the amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius. It is essential in calculating the heat required for changing the temperature of substances, enabling the determination of how much energy the hot tea loses as it cools from one temperature to another.

Conservation of Energy

In thermodynamic processes, the conservation of energy principle states that the energy within a closed system remains constant. This concept is used to set up energy balance equations where the heat lost by one component, such as hot tea cooling, is equal to the heat gained by another component, like ice melting and warming, ensuring that the total energy of the system is conserved.
