	This is opposed to solid resources, processed irreversibly from ores into pure ingots and alloys, used directly for crafting purposes. Gases have a great variety of uses - some are required for creation of livable pressurized environments, while others are toxic and dangerous and meant for controlled industrial processes, or outright waste product with limited utility.

Gases have a great variety of uses - some are required for creation of livable pressurized environments, while others are toxic and dangerous and meant for controlled industrial processes, or outright waste product with limited utility.

	Naturally, gases can exist as a constituence of a planetary atmosphere, available in a virtually infinite amount and possible to capture through the use of appropriate atmospheric devices, can be pressurized, filtered, and stored. Planets or moons that have a below-zero or vacuum conditions will also contain frozen gas deposits in a form of ice, which can be melted by the use of a [[Furnace]] or [[Ice Crusher]]. Also, mined ice nuggets appear similar to metallic ores, however they will begin to melt if exposed to a warm environment while held in arms or regular containers.

It is technically possible to convert gases down into their solid state (i.e. a physical item), however that action has limited practical use, beyond perhaps hand measuring of specific quantities, and no dedicated devices exist for doing so.		Gases and their liquid analogues are presented in the parametric form - that means that they exist as a property of a given atmosphere' [[grid]] cell, interior grid cell of an enclosed [[room]], composite [[pipe]] network, atmospheric device, or portable container. To further understand the behavior of gases within different spaces, check [[Atmosphere]] and [[Pipe]] pages.

	Each different gas have a number of properties, which define its thermodynamic behavior and conditions for phase changes. Leveraging the property values and their differences between gases is an important part of atmospheric management and temperature conditioning required for surviving extreme environments and utilizing advanced technologies:		Each different gas have a number of properties, which define its thermodynamic behavior and conditions for phase changes. Leveraging the property values and their differences between gases is an important part of atmospheric management and temperature conditioning required for surviving extreme environments and utilizing advanced technologies:
	* '''Melting Point''' - Temperature boundary between solid and liquid states. Liquids cooled to this temperature will begin freezing. This will create ice chunks converting up to 50 mol of liquid into a 50g stack of pure ice. Liquids freezing within containers or pipes will cause them to burst irreversibly. A player should make sure never to cool the gas down to this value.		* '''Melting Point''' - Temperature boundary between solid and liquid states.

	* '''Boiling Point''' - Temperature boundary between liquid and gaseous states at standard 1 atm (100 kPa) of pressure. Higher pressures impede evaporation, raising this value and allowing to form liquids at higher temperatures. Most atmospheric devices are designed to work with gases, while liquified substances are very compact. Player should control pressure and temperature to prevent gases and liquids reaching this value unintentionally. Not available for substances, that will remain in gaseous phase at 100 kPa regardless of temperature.		* '''Boiling Point''' - Temperature boundary between liquid and gaseous states at standard 1 atm (100 kPa) of pressure.

	* '''Minimum Condensation Pressure''' - a Pressure value corresponding to the Melting Point Temperature, which is necessary for the liquid to begin freezing. Most liquified gases will freeze up when cooled below their melting point regardless, but for ''some'' gases a low pressure environment can be sustained to keep a liquid in a super-cooled state without allowing it to crystallize, which is useful for storage of few particular substances.		* '''Minimum Condensation Pressure''' - a Pressure value corresponding to the Melting Point Temperature, which is necessary for the liquid to begin freezing.

	* '''Maximum Liquid Temperature''' - a Temperature value, above which the substance cannot remain in liquid state within working pressure range, usually sampled at high pressure (6 MPa). Exponentially higher pressures are capable of keeping the liquid from evaporating, but the requirements are unrealistic for physical limitations of Stationeers' equipment. Its a practical heat boundary, under which a given substance can be either gas, liquid, or both based on the imposed pressure level, all the way down to the melting point boundary.		* '''Maximum Liquid Temperature''' - a Temperature value, above which the substance cannot remain in liquid state within working pressure range, usually sampled at high pressure (6 MPa).

	* '''Molar Heat Capacity''' - The thermal capacity of 1 mol of the gas, that it has to absorb/radiate to raise/lower its temperature by 1 K. The greater this value, the more heat a cold gas can absorb to cool another gas, and inversely, the more heat has to be drawn out to cool it. Particularly important value for an efficient coolant.		* '''Molar Heat Capacity''' - The thermal capacity of 1 mol of the gas, that it has to absorb/radiate to raise/lower its temperature by 1 K.

	* '''Molar Heat of Fusion''' - The amount of thermal energy that a mol of frozen substance would need to absorb to change into a liquid, and the amount of same energy a liquid will release into environment when turning into ice. Given that frozen substances are rarely used as anything beyond a raw source material for gases, this value has little importance.		* '''Molar Heat of Fusion''' - The amount of thermal [[energy]] that a mol of frozen substance would need to absorb to change into a liquid, and the amount of same energy a liquid will release into environment when turning into ice. Given that frozen substances are rarely used as anything beyond a raw source material for gases, this value has little importance.

	* '''Molar Latent Heat''' - The amount of thermal energy that a mol of liquid substance would need to absorb to change into a gas, and the amount of same energy a gas would release when turning into a liquid. This value is something that is often leveraged in AC or any temperature control systems, by forcing phase changes at specific points of a system through applied pressure. It is also likely responsible for the majority of confusing and frustrating emergencies for inexperienced Stationeers, where temperatures suddenly spike or drop to dangerous levels, seemingly for no reason.		* '''Molar Latent Heat''' - The amount of thermal energy that a mol of liquid substance would need to absorb to change into a gas, and the amount of same energy a gas would release when turning into a liquid.

	* '''Molar Liquid Volume''' - Volume in Liters that a mol of substance occupy in liquid form. Since liquified gases produce no Pressure, this value defines how much of a given liquified gas can be stored in a liquid container or pipe network of a certain capacity.		* '''Molar Liquid Volume''' - Volume in Liters that a mol of substance occupy in liquid form.

	* '''Molar Mass''' - Net mass of a mol of substance in any phase state. Largely redundant parameter that becomes important when dealing in Rocketry, since the rocket engines have specific limits to what mass they're able to carry into space against a local gravity, and excessive amount of fuel/payload can make a lift-off impossible.		* '''Molar Mass''' - Net mass of a mol of substance in any phase state.
