A $50.0$ -g sample of water at $100.00^{\circ} \mathrm{C}$ was placed in an insulated cup. Then $25.3 \mathrm{~g}$ of zinc metal at $25.00^{\circ} \mathrm{C}$ was added to the water. The temperature of the water dropped to $96.68^{\circ} \mathrm{C}$. What is the specific heat of zinc?

Key Concepts

Specific Heat

Specific heat is a physical property of matter that describes the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius (or one Kelvin). It is a key concept in thermodynamics and helps in understanding how different substances resist temperature change when heat is added or removed.

Calorimetry

Calorimetry is the experimental method used to measure the amount of heat exchanged in a chemical or physical process. By observing temperature changes in a system (typically an isolated system), calorimetry applies the principle of energy conservation to calculate heat flow between substances.

Heat Transfer

Heat transfer refers to the process by which thermal energy is exchanged between physical systems or objects. This exchange occurs until thermal equilibrium is reached and is governed by the properties of the materials involved, such as specific heat.

Conservation of Energy

The conservation of energy principle states that energy cannot be created or destroyed, only transformed or transferred from one form to another. In the context of heat exchange in calorimetry, it means that the total heat lost by one part of the system must equal the total heat gained by another part, allowing for calculations involving specific heat and temperature changes.
