# Rule of Mixtures Calculator for Heat Capacity

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. 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 \(m_{1}+m_{2}\)
