Right. And you'd want to be sure the initial air was as dry as possible. I think a Mason jar would do just fine. (I've never heard of "silanized" glass.) And, like you say, we'd want to allow the lid to be loose to allow for displacement up until the drop has evaporated.

You believe there will be enough displacement to compensate for the added weight of the drop. I believe that there will be some displacement but not enough to compensate for the added weight of the drop.

I would also suggest it be done in a warm and dry setting to discourage any condensation on the metal lid.

Mass will be higher.

but he is right. take a container of air, weigh it. write that down.

now add 1 drop of water to the container.

it HAS to be heavier !

After providing more energy
that is needed for boiling out the same amount at 100 deg C,
the water evaporates.

Than it will be lighter, when less dense vapour
pushed out denser air during pressure balance.

indeed,

latent heat is interesting and complicated, a nice Psychrometric chart
here;

http://www.shadyattia.net/academic/BioclimaticDesign/Lecture%2007.html

http://img.techpowerup.org/060417/psychrometric_chart.gif

however I am sure Enthalpy, Psychrometric, latent heat, is WAY over head
of OP.


the charts do not show the pressure parameter, etc.........

Actually I mispoke here. After the drop has evaporated the humidity inside the jar should be greater than it was before the drop of water was allowed to evaporate. The evaporate will have forced some of the air out of the top of the container. Both Poutin and I agree on this.

Poutin believes the H2O particles that remain in the jar will be monomolecular (cold steam). And since the molecular weight of the H2O molecules is 18 and the molecular weight of the N2 and O2 that is replaces is, on average, 29 the weight of the contents of the jar will be less than they were before the drop of water was places in the jar.

I believe the H2O particles left in the jar will be multimolecular, clumps/droplets. My guess is that these drops will be at least 10 molecules per particle. Thus the particle size will be at least 180. Also, there will be 1/10 as many particles than there would be if they were monomolecular. For both of these reasons the number of particles that are pushed out of the top will be fewer, thus resulting in fewer particles forces out of the top of the jar and the weight of the remaining particles will be on average greater. And as long as the humidity in the jar is greater than that beforehand the jar will measure heavier.

LOL. We both believe. Remember, your "knowledge" is based on books you can't find.

That is a formula.

The point is, if you understood it, you would need any data.
All will be result as implications of this formula.

no wonder you cannot understand anything in sci.physics, even so, there
are calculators online you can use.

so James, are you a high school dropout ?

Yes, I believe formulas need data to be of any use.

yep, you silly and uneducated, and have a weak mind. Accept that fact.
Formulas describe relationships between parameters.
