In the diagram below, particles of the substance are moving from the liquid phase to the gas phase at the same rate as they move from the gas phase to the liquid phase.

The gas and liquid are at...
~ equilibrium.
~ a high vapor pressure.
~ a low vapor pressure.
~ zero vapor pressure.

Hi :)

danjs · Answer

The definition of equilibrium in this case, is the # of molecules entering the gas phase equals the number of molecules leaving the gas phase. So the net effect is nothing happening.

anonymous · Answer

So would it just be equilibrium or zero vapor pressure?

Oh thank you for the chart. It definitely helps.
So it would be equilibrium.

danjs · Answer

vapor pressure depends on a couple factors

danjs · Answer

yeah equilibrium for sure

anonymous · Answer

Thank you (yet again)!

danjs · Answer

so the vapor pressure would depend on the type of substance and temperature

danjs · Answer

welcome :)

Oh okay. That makes sense.
