2019年4月13日 · Methane "snow" would be white. (Due to scattering of light). Solid methane under sufficient pressure would form a clear colorless solid. Methane "snow" (which would be …
What is the density of solid methane at atmospheric pressure?
2024年7月19日 · I'm curious about the density of solid methane since it might be slightly more energy dense than liquid natural gas. The materials project computes the density to be 0.433 …
If we start heating a substance, does it melt when we break its ...
2018年1月8日 · So generally we take solid and heat it. When (IF!) it turns to a liquid then the temperature of the transition is the melting point. Likewise if the liquid can be turned into a …
What properties a compound should have to be called an "ice"?
$\begingroup$ I think "ice" in chemistry is formally used only to refer to water in the solid state. Wikipedia has an astronomical definition for ice based loosely on the melting/boiling points of …
What chemicals could absorb/adsorb ambient atmospheric …
There are materials that absorb methane under ambient conditions. A quick Google Scholar search for "metal organic framework methane" shows some of the most recent and popular …
Why is CH4 a gas at room temperature but CH3Cl a liquid?
2015年11月16日 · The dipole-dipole interactions are much stronger than the van der Waals interactions present in methane, so it’s boiling point is much higher. When comparing …
At what temperature CO2 becomes solid at normal pressure?
