At first must collect it. This can be completed by piping it via a tube, which comes out beneath a bowl of water with an upside down test tube over it. Now subsequent to collecting the gas cork it.
Now get rid of the cork and put in a light splint. If it is hydrogen, then it will burn with a squeaky pop.
The vapor pressure of small liquid drops depends on the drop size. Although the surface properties of a liquid are different from those of the bulk liquid, the special surface properties can be ignored except in a few situations. One is the case in which a liquid is dispersed into fine dr
