04 - Dry Ice Rapid Sublimation

Very simple to perform. Just break up dry ice into small chunks, put into a container, and pour hot water over the frozen carbon dioxide. Very cool and interesting.



Grams of dry ice in one cubic centimeter: The density of dry ice is 1.562g/mL. Granted now that one milliliter takes up the space of about one cubic centimeter.

Now convert to moles in order to use the ideal gas law...

1.562g • (1mol CO2/44.01g/mol) = 0.03549mol CO2

PV=nRT ... V=nRT/P

Volume = (0.03549mol • 0.08206L•atm/K•mol • 298 K)/(1 atm) = 0.8679L CO2(g) per gram of CO2(s)
(Significant figures are overrated, most of the time.)



I created this channel for the sole purpose to help spread the interest in science, mainly chemistry. The decline of scientific interest in the United States is rather disappointing. After I cruised YouTube a bit I noticed all the other channels similar to mine and I thought about canceling this channel; however, after thinking about the decline of science, I decided to keep making videos until I just run out of ideas.


Once (if) I get a few more subscribers, I'll upload a couple videos using the liquid metal mercury!

so if i were to heat a diamond to 3000+ celcius i am gonna get the same effect?

[666TECHNO666]

use this instead of wasting 300+ on a fog machine for part's :)

[DomoXDWobbuffet]

wow this is so cool

[Myfanwy94]

oh man you could had make with dry ice sulfur chlorides and sulfuryl chloride.
