What physical process could you use to remove the water vapor from the sample?

Answer 1

You usually use a vacuum oven. The vacuum lowers the vapor pressure of the water and heat make the water more volatile so the sample dries quickly. Exhaust gases are collected in a dry ice trap to prevent accidental contamination of sewer water.

Answer 2

A sample of what? You could use a desiccant or use temperature and pressure to liquefy and remove the vapor. Gravity could also work if the gasses you wanted to separate it from where significantly lighter or heavier. You might even be able to use an electric charge.

Answer 3

a sample of what?

air = cool it to 32 degrees F. all water vapor should loose it's latent heat of vaporization and collect in the bottom where it will become ice.

from an object...I use ultra pure N2 to dry things out without heat or you can use hot N2 as well

Answer 4

Heating process...

In Air conditioning:
indoor temperature is the result of a balance among heat gain, heat loss, and heat storage,so is indoor humidity the result of moisture gain,moisture loss, and moisture storage.

In formula this can be simply expressed as:
Qg-Qr=Qs
where Qg = water vapor gain, kg/s (lb/h)
Qr = water vapor removal rate, kg/s (lb/h)
Qs = moisture storage rate, kg/s (lb/h)

Answer 5

Either pass the gas through calcium carbonate, which removes the water, or cool it to have the vapor condense and/or freeze.

Answer 6

Sample of what?
depending on what else is in your sample, you could heat it in order to evaporate the water, as long as it has the lowest boiling point. You can also use a drying agent like sodium sulfate (anhydrous).

Answer 7

Distillation, filter, and an absorbent.
