Can liquid methane freeze?
Our recent work has shown that although methane and ethane have similar freezing points (~91 K), when mixed they can remain liquid down to 72 K.
What is the temperature to freeze methane?
Question: The freezing point of methane is -295 F and the boiling point is -263 F.
What temperature does liquid methane freeze in Celsius?
The temperature of the surface of Titan, a moon of Saturn, is 93 K.
How cold is liquid methane?
Consider the following: Liquid hydrogen fuel used by the space shuttle must be stored at a temperature of -252.9°C—only about 20 degrees above absolute zero! Liquid methane, on the other hand, can be stored at the much warmer and more convenient temperature of -161.6°C.
Can you swim in liquid methane?
You're going to sink, and probably fast. With its low viscosity, or, uh, gooiness, and low surface tension, even the smallest bug would fall right through the surface of liquid methane. And liquid methane has a low density. So as you swim, every stroke will have less force than if you were treading water.
Did the lake on Titan freeze or evaporate?
The lake disappeared during Titan's summer, when the amount of energy being transferred into the lake was higher than at other times, so the lake must have evaporated, not frozen. How they figure it out: In the Sim, they investigate how adding or removing energy can affect molecules' freedom of movement.
What temperature does liquid methane evaporate?
Previous experiments show the average pure methane evaporation rate to be (3.1 ± 0.6) × 10-4 kg s-1 m-2 at an average temperature of 94.1 ± 0.6 K (6, 9).
Did the methane lake on Titan freeze or evaporate?
The lake disappeared during Titan's summer, when the amount of energy being transferred into the lake was higher than at other times, so the lake must have evaporated, not frozen. How they figure it out: In the Sim, they investigate how adding or removing energy can affect molecules' freedom of movement.
Is liquid methane cryogenic?
Liquid methane is a cryo-genic (extremely cold) liquid that also happens to be flammable. The temperature difference between the flame and the liquid methane right below it is over 3000°F!
Can humans swim in liquid methane?
With its low viscosity, or, uh, gooiness, and low surface tension, even the smallest bug would fall right through the surface of liquid methane. And liquid methane has a low density. So as you swim, every stroke will have less force than if you were treading water.
What if you jumped into a pool of liquid methane?

Is liquid methane flammable?
Methane is an explosion hazard in enclosed areas. Liquefied Methane floats on water and boils. The vapor cloud produced is FLAMMABLE. POISONOUS GASES ARE PRODUCED IN FIRE.
Why did the methane lake on Titan disappear?
The lake disappeared during Titan's summer, when the amount of energy being transferred into the lake was higher than at other times, so the lake must have evaporated, not frozen.
At what temperature does methane evaporate?
The boiling point of methane is −162 °C (−259.6 °F) and the melting point is −182.5 °C (−296.5 °F). Methane in general is very stable, but mixtures of methane and air, with the methane content between 5 and 14 percent by volume, are explosive.
Can liquid methane ignite?
Methane is nontoxic, yet it is extremely flammable and may form explosive mixtures with air.
Did the lake on Titan evaporate or freeze?
The lake disappeared during Titan's summer, when the amount of energy being transferred into the lake was higher than at other times, so the lake must have evaporated, not frozen. How they figure it out: In the Sim, they investigate how adding or removing energy can affect molecules' freedom of movement.
How is liquid methane stored?
Methane is mainly stored in micropores (<2 nm) or mesopores (2–50 nm) at supercritical temperature (above 273.15 K) over a wide range of pressures (up to 50 MPa) in shale gas reservoirs and vehicular applications.
Why is rocket fuel so cold?
Liquid oxygen is naturally quite cold, as gases compressed into fluid tend to be. Making it extra-cold—down to around -207° C—makes it even denser, allowing you to store more of it in the same-size tank and increasing your rocket's efficiency.
What does liquid methane smell like?
The distinctive smell you might associate with methane is actually another gas (methanethiol), which is added to consumer methane for safety. Methanethiol is often described as smelling like rotten eggs, and the human nose can detect it down to the parts-per-billion level.
Is the water on Titan drinkable?
Titan is going to have methane and ethane tainting the ice. And Enceladus and Europa are going to be all kinds of salts and possibly magnesium sulphate, or epsom salts if it's hydrated. So if you drink that water you'll be trotting off to the loo quite soon.
Can you float on liquid methane?
The density of liquid methane is much, much lower than water, so you wouldn't be as buoyant.
At what temperature does methane ignite?
Spontaneous ignition temperatures for stoichiometric methane-air mixtures are around 870 K (600°C) at atmospheric pressure and decrease to 660 K (390°C) at 1100 bar ignition pressure.
At what temperature does liquid methane evaporate?
Previous experiments show the average pure methane evaporation rate to be (3.1 ± 0.6) × 10-4 kg s-1 m-2 at an average temperature of 94.1 ± 0.6 K (6, 9).
Did Titans lake evaporate or freeze?
The lake disappeared during Titan's summer, when the amount of energy being transferred into the lake was higher than at other times, so the lake must have evaporated, not frozen. How they figure it out: In the Sim, they investigate how adding or removing energy can affect molecules' freedom of movement.
Can liquid methane evaporate?
Methane tends to evaporate quickly, so scientists think the lakes must be dominated by methane's sister hydrocarbon ethane, which evaporates more slowly.
What temp does methane ignite?

Is the methane on Titan flammable?
On Earth, methane is a flammable gas, but Titan has no oxygen in its atmosphere that could support combustion.
What is the white smoke that comes out of rockets?
(All that swirling white “smoke” before a launch is actually the cold liquid oxygen venting out and condensing water vapor in the air1.) And you need to continuously top off any oxygen that does escape before launch. SpaceX is making it even harder on themselves—cooling the oxygen down another 40 to -340 degrees F.
Why doesnt a rocket engine melt?
In fuel rich combustion, a lot of carbon is left unburnt and can create soot. You can see this in the exhaust of the gas generator for the Merlin engine. In this engine, SpaceX runs the gas generator extremely fuel rich, which reduces the temperature enough to stop the turbine from melting.
Why does my house suddenly smell like cat pee?
Multiple things can cause your house to smell like cat urine, even if you don't have a cat. Investigate if there is mold, leaking Freon, sewer gases, smelly plants, spoiled food, or even stains from previous pet owners.
