Calculadora de Calorimetria

The Calorimetry Calculator determines the final equilibrium temperature when two bodies with different masses, specific heats, and initial temperatures are placed in thermal contact in an isolated system. It uses the principle of energy conservation, where the heat lost by the hotter body equals the heat gained by the colder body. The formula used is T_f = (m₁c₁T₁ + m₂c₂T₂) / (m₁c₁ + m₂c₂), where m is mass, c is specific heat, and T is initial temperature.

To use the calculator, enter the values of mass (in grams or kilograms), specific heat (in J/g°C or J/kg°C), and initial temperature (in °C) for each body. The calculator then computes the final equilibrium temperature. It is important that units are consistent: if mass is in kg, specific heat must be in J/kg°C; if in g, specific heat must be in J/g°C. The result is given in the same temperature unit entered.

This calculator is useful in everyday and academic situations, such as mixing hot and cold water to achieve a desired temperature, determining the final temperature when placing a hot object into a cold liquid, or in physics and chemistry laboratory experiments. It can also be applied in engineering for heat exchanger designs or heating and cooling systems.

Important precautions: the calculator assumes the system is isolated, meaning no heat loss to the environment. In practice, this is not entirely true, so the result is an approximation. Additionally, the formula is only valid if there is no phase change (such as melting or vaporization) during the process. If phase change occurs, latent heat must be considered, which this calculator does not do.
