The inner vessel of a calorimeter contains $2.50 \times 10^{2} \mathrm{g}$ of tetrachloromethane, $\mathrm{CCl}_{4},$ at $40.00^{\circ} \mathrm{C} .$ The vessel is surrounded by $2.00 \mathrm{kg}$ of water at $18.00^{\circ} \mathrm{C} .$ After a time, the $\mathrm{CCl}_{4}$ and the water reach the equilibrium temperature of $18.54^{\circ} \mathrm{C} .$ What is the specific heat of $\mathrm{CCl}_{4} ?$

Key Concepts

Thermal Equilibrium

Thermal equilibrium is reached when two or more interacting substances come to the same temperature and no net heat flow occurs between them. This concept is essential in calorimetry because it provides the condition needed to apply energy conservation equations effectively in order to determine unknown heat capacities.

Conservation of Energy

The principle of conservation of energy states that in an isolated system, the total energy remains constant. In calorimetric experiments, this means that the heat lost by hotter substances is equal to the heat gained by cooler substances, enabling calculations of unknown thermal quantities.

Specific Heat Capacity

Specific heat capacity is a physical property that indicates the amount of heat required to raise the temperature of one unit mass of a substance by one degree Celsius (or one Kelvin). It is a crucial parameter in thermal calculations, allowing the quantification of how substances respond to heat transfer.

Calorimetry

Calorimetry is the study of measuring the heat exchanged in physical and chemical processes, commonly by using devices called calorimeters. It involves analyzing how energy is transferred between substances, often through temperature changes, in order to determine unknown thermal properties such as the specific heat capacity of a material.
