## About Praseodymium

Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. Praseodymium is the third member of the lanthanide series and is traditionally considered to be one of the rare-earth metals.

## Praseodymium – Specific Heat, Latent Heat of Fusion, Latent Heat of Vaporization

**Specific heat of Praseodymium is ****0.19 J/g K**.

**Heat capacity** is an extensive property of matter, meaning it is proportional to the size of the system. **Heat capacity C** has the unit of energy per degree or energy per kelvin. When expressing the same phenomenon as an intensive property, the **heat capacity** is divided by the amount of substance, mass, or volume, thus the quantity is independent of the size or extent of the sample.

**Latent Heat of Fusion of Praseodymium is ****6.89 kJ/mol**.

**Latent Heat of Vaporization of Praseodymium is ****296.8 kJ/mol**.

Latent heat is the amount of heat added to or removed from a substance to produce a change in phase. This energy breaks down the intermolecular attractive forces, and also must provide the energy necessary to expand the gas (the **pΔV work**). When latent heat is added, no temperature change occurs. The enthalpy of vaporization is a function of the pressure at which that transformation takes place.
