Question

When a system has constant vapor pressure, what exists between the liquid and its vapor?

Answer 1

`"A phase equilibrium.....?"`

Explanation:

`"Liquid"stackrel("constant temperature")rightleftharpoons"Vapour"`

And here, given a specific temperature, the rate of vaporization should be equal to the rate of condensation...of course, when we hang out the washing on the clothes-line, a closed system no longer operates, and the washing gets dry eventually...
