You can solidify oxygen using an environment with substantial pressure and extremely cold temperatures correct?

 

Also, can you make like mercury or Iron Gas?

See the thing on the right that says freezing point? That's for atmospheric pressure.

 

Mercury is regularly distilled to purify it. Good reagent grade material is triple-distilled.

 

Iron can certainly be vaporized, but would react readily with oxygen if not under vacuum or inert gas blanket.

Same deal. Note how extremely high the temperature is. This would probably best be done using an electric arc furnace.

Lets say I put O2 in an environment with 10 atmospheres of pressure. I would only need to decrease the temprature of the O2 to 1/10 of -218.79 °C.

Or is pressure and temperature not directly proportional?

 

Same goes for Iron, except its 0 atmospheres of pressure, it should be 1/2 of 2862 °C the temperature to force iron into a gasseous state.

 

 

O2 : -21.8 *C

Fe : 1431 *C

doesn't work like that. it is not a linear relationship at all.

 

look up P-T phase diagrams. they show the relationship between state temperature and pressure.

Also, if you ever multiply or divide a temperature (not a temperature difference though), then you need to use an absolute measure of temperature, like Kelvin. Otherwise the division will depend on where on your scale absolute zero is.

AH yes, i forgot about kelvin and its relationship to chemistry in mathematics.
