A combination of 0.250 $\mathrm{kg}$ of water at $20.0^{\circ} \mathrm{C}, 0.400 \mathrm{kg}$ of aluminum at $26.0^{\circ} \mathrm{C},$ and 0.100 $\mathrm{kg}$ of copper at $100^{\circ} \mathrm{C}$ is mixed in an insulated container and allowed to come to thermal equilibrium. Ignore any energy transfer to or from the container. What is the final temperature of the mixture?

Key Concepts

Heat Transfer

Heat transfer refers to the movement of thermal energy from a hotter object or region to a cooler one. This process occurs through conduction, convection, or radiation, but in an insulated system, only the internal transfers of heat between substances occur without any external losses.

Conservation of Energy

The principle of conservation of energy states that energy cannot be created or destroyed in an isolated system. When substances at different temperatures are mixed, the heat lost by the hotter substances must equal the heat gained by the cooler ones, allowing for the calculation of the final equilibrium temperature.

Specific Heat Capacity

Specific heat capacity is a material property that quantifies the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius (or Kelvin). It is crucial in calculating how much heat is absorbed or released when a substance's temperature changes.

Thermal Equilibrium

Thermal equilibrium is the state in which all parts of a system eventually reach the same temperature, so that no net heat flow occurs between them. In the context of mixing substances with different initial temperatures, the system evolves to this uniform temperature due to the equalization of thermal energy.
