Rule of Mixtures Calculator for Heat Capacity

The mass of each individual component is equivalent to the total mass of the mixture, which can theoretically be broken down into separate parts.

Heat capacity is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change. Specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The heat capacity of a mixture can be calculated using the rule of mixtures.

The new heat capacity depends on the proportion of each component, which can be calculated from mass or volume. Using the mass and specific heat capacity of each component, the Rule of Mixtures Calculator calculates the specific heat capacity of the entire sample. If mass is used for one component, it must be used for all components, similarly for volume. The units of mass or volume don’t matter, as long as they match; eg: if ml are used for one component, they must be used for all components.

 

\[C_{p\,mixture}=\Big(\frac{m_{1}}{m_{mixture}}\Big)C_{p\,1}+\Big(\frac{m_{2}}{m_{mixture}}\Big)C_{p\,2}\]

Where:
\(C_{p}\) = Heat Capacity
\(m\) = Mass
\(m_{mixture}\) is \(m_{1}+m_{2}\)
