A $150.0-\mathrm{g}$ sample of a metal at $75.0^{\circ} \mathrm{C}$ is added to $150.0 \mathrm{~g} \mathrm{H}_{2} \mathrm{O}$ at $15.0^{\circ} \mathrm{C}$. The temperature of the water rises to $18.3^{\circ} \mathrm{C}$. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the metal is gained by the water.

Key Concepts

Specific Heat Capacity

Specific heat capacity is the energy required to raise one gram (or one kilogram) of a substance by one degree Celsius (or Kelvin). It is an intrinsic property that indicates how a material responds to the addition or removal of heat, and it is essential in determining temperature changes during thermal interactions.

Calorimetry

Calorimetry is the experimental process used to measure the amount of heat exchanged in physical or chemical processes. It involves observations on temperature changes in an isolated system, allowing the determination of thermodynamic properties such as specific heat capacity.

Conservation of Energy in Heat Transfer

The principle of conservation of energy in heat transfer states that in an isolated system, the heat lost by a hotter object must equal the heat gained by a colder object. This fundamental concept underpins the methods used in calorimetric measurements and calculations involving thermal equilibrium.

Heat Transfer Equation (Q = mc?T)

The heat transfer equation, expressed as Q = mc?T, relates the heat energy exchanged (Q) to the mass (m) of the substance, its specific heat capacity (c), and the change in temperature (?T). This equation is pivotal for calculating unknown quantities in experiments where temperature changes are measured.
