Non-vaporizable
The term "non-vaporizable" describes a substance or material that does not readily change from a solid or liquid state into a gaseous state, even under increased temperature or pressure. This characteristic is determined by the substance's intermolecular forces, its boiling point, and its thermal stability. Substances described as non-vaporizable possess strong cohesive forces between their molecules, inhibiting their ability to overcome these forces and transition into the vapor phase easily. This lack of volatility makes them useful in various applications where stable, non-gaseous forms are desired.
Non-vaporizable meaning with examples
- Ceramic materials, like porcelain or alumina, are excellent examples of non-vaporizable substances. They remain solid even at extremely high temperatures, making them suitable for high-temperature applications such as furnace linings and crucibles. The robust bonds between the atoms prevent vaporization. Therefore, a ceramic oven can be used for pizza.
- Many salts, like sodium chloride (table salt), are considered non-vaporizable under ordinary conditions. While they can be sublimated at very high temperatures, their tendency to remain solid is why salt is often used to preserve food by dehydrating it. Vaporization is typically a slow or negligible process.
- High-molecular-weight polymers, such as certain plastics or rubber compounds, are often non-vaporizable at standard temperatures and pressures. The long, complex chains of polymer molecules contribute to a significant resistance to vaporization. Rubber tires for vehicles can be utilized without them turning into a gas.
- In the context of nuclear materials, certain heavy elements, such as uranium oxide, can be considered non-vaporizable under most circumstances. This characteristic is crucial for the safe handling and storage of nuclear fuel. The structure and strength between atoms of this material would prevent evaporation.
