You add $100.0 \mathrm{~g}$ water at $60.0^{\circ} \mathrm{C}$ to $100.0 \mathrm{~g}$ ice at $0.00^{\circ} \mathrm{C}$. Some of the ice melts and cools the water to $0.00^{\circ} \mathrm{C}$. Calculate what mass of ice has melted when the ice and water mixture reaches a uniform temperature $$ \text { of } 0^{\circ} \mathrm{C} $$

Key Concepts

Thermal Equilibrium

Thermal equilibrium is the state reached when two or more substances in thermal contact no longer exchange heat, resulting in a uniform temperature throughout the system. Achieving thermal equilibrium is a key condition in solving problems involving heat transfer between substances at different initial temperatures.

Latent Heat of Fusion

The latent heat of fusion refers to the amount of energy required to change a unit mass of a substance from a solid to a liquid at its melting point, without a temperature change. This concept is essential when dealing with phase transitions such as the melting of ice.

Conservation of Energy

This principle states that energy cannot be created or destroyed in an isolated system but can only change forms. In thermal processes, the heat lost by a warmer substance must equal the heat gained by a cooler one, ensuring an energy balance during temperature changes and phase transitions.

Specific Heat Capacity

Specific heat capacity is the amount of energy required to raise the temperature of a unit mass of a substance by one degree in temperature. It is a crucial concept for calculating the energy changes involved when substances change temperature without undergoing a phase change.
