Tiiviskaasuksi

Tiiviskaasuksi is a Finnish term that translates to "condensed gas" or "liquefied gas." It refers to a gas that has been cooled to a low temperature or compressed to a high pressure, or a combination of both, causing it to change from a gaseous state to a liquid state. This process is essential for the storage, transportation, and use of many gases.

Common examples of tiiviskaasuksi include liquefied petroleum gas (LPG), which is primarily propane and butane, and liquefied natural gas (LNG), which is mainly methane. These gases are stored and transported as liquids because they occupy significantly less volume in this state compared to their gaseous form, making them more economical and practical.

The liquefaction process typically involves removing heat from the gas until its temperature drops below its boiling point at a given pressure. Alternatively, pressure can be increased sufficiently at a constant temperature to force the gas into a liquid state. Maintaining tiiviskaasuksi in its liquid form requires specialized insulated containers or cryogenic tanks that prevent it from warming up and re-vaporizing.

The applications of tiiviskaasuksi are widespread. LPG is commonly used as fuel for heating, cooking, and in vehicles. LNG is a growing alternative fuel for transportation and power generation. Other gases like oxygen, nitrogen, and argon are also liquefied for industrial and medical purposes, allowing for their efficient storage and transport.
