(II) A cube of ice is taken from the freezer at $-$8.5$^\circ$C and placed in an 85-g aluminum calorimeter filled with 310 g of water at room temperature of 20.0$^\circ$C. The final situation is
all water at 17.0$^\circ$C. What was the mass of the ice cube?

Key Concepts

Conservation of Energy

This concept involves the principle that energy cannot be created or destroyed, only transferred. In a calorimetry context, the energy lost by one part of the system is equal to the energy gained by another, ensuring that the total energy remains constant. This principle is crucial in solving problems where different components exchange heat until thermal equilibrium is reached.

Calorimetry

Calorimetry is the measurement of heat transfer during a physical or chemical process. It involves determining the amount of heat absorbed or released by substances during changes in temperature or phase, using instruments like calorimeters. The method relies on precise measurements and the use of specific heat capacities and latent heats to calculate energy changes.

Specific Heat Capacity

Specific heat capacity refers to the amount of heat energy required to raise the temperature of one unit mass of a substance by one degree. It is a critical parameter in heat transfer problems, as it allows us to calculate the energy change associated with temperature variations in a material.

Latent Heat of Fusion

Latent heat of fusion is the amount of energy required to change a substance from solid to liquid at its melting point without changing its temperature. This concept is essential in scenarios involving phase changes, where energy is absorbed or released during the transition despite a constant temperature.

Phase Change

Phase change describes the transition of a substance from one state of matter (e.g., solid, liquid, gas) to another. During the transition, the substance absorbs or releases latent heat without a change in temperature, which is a key consideration when evaluating systems that include melting or freezing processes.
