What process is required to change water at 32 degrees F into ice at 32 degrees F?

• A. Latent heat of fusion
• B. Latent heat of vaporization
• C. Specific heat capacity
• D. Convection cooling

Answer: (A)

To change water at 32 degrees Fahrenheit into ice at the same temperature, the concept of latent heat of fusion is crucial. Latent heat of fusion refers to the amount of thermal energy needed to change a substance from a liquid phase to a solid phase without changing its temperature. In this situation, water at 32 degrees F is at its freezing point. To convert this water into ice, energy must be removed from the water. By removing this energy, the molecules of water lose kinetic energy and begin to form a solid structure—ice—while remaining at a constant temperature of 32 degrees F during this phase change. The other concepts mentioned do not apply to this specific process. For instance, latent heat of vaporization pertains to the heat energy required to turn a liquid into a gas, which is not relevant here. Specific heat capacity relates to the amount of energy needed to change the temperature of a unit mass of a substance by one degree, which also does not involve a phase change. Convection cooling involves transferring heat through fluid motion, which is not the primary mechanism for changing water into ice at 32 degrees F. Thus, the correct process needed to accomplish the change from water to ice at the same temperature is the latent heat
