You are watching: What is meant by a saturated liquid and vapor
$egingroup$ In mine mind a Saturated liquid is a "mixture" of all liquid through a as tiny as possible steam bubble, in the same way a Saturated steam is a "mixture" that all vapor with a as little as feasible liquid drop. Is the correct? $endgroup$
The distinction is simply that: one is in the fluid phase and the other is in the vapor phase.
A material like water has a particular temperature in ~ which that boils. This temperature alters with approximately pressure, such the a low pressure synchronizes to a short boiling allude temperature and also a high pressure rises the boiling allude temperature.
When a saturation problem is reached, the liquid phase and also the vapor phase are in equilibrium v one another, i.e., both phases deserve to exist simultaneously. If a small amount of power is added to saturation liquid, it turns right into vapor at continuous temperature. Likewise, if a little amount of power is removed from saturation vapor, it will condense to fluid at const. Temp.

$egingroup$ for this reason the distinction is because of the non best behaviour of substances, prefer water? If lock were best the change from liquid to vapor phase will be instantaneous without intermediate states? $endgroup$

$egingroup$ ns agree through you, and by intermediate claims I typical the two-phase states. $endgroup$

this is incredibly late, but for human being still googling this question: I recognize it together Hg gift the vapour state with nearly 0 liquid state. The quality x of this would 1. And the saturated liquid state is whereby the fluid is ~ above the cusp of an altering state, thus an infinitesimal lot of the liquid has actually vaporised, v a subsequent quality x would certainly be 0. Represent saturated liquid state together Hf.

From "Thermodynamics: an design approach", by Yunus A. Çengel, Michael A. Boles:
Consider a piston–cylinder maker containing liquid water in ~ 20°C and 1 atm pressure being heated. Under this conditions, water exists in the fluid phase, and it is referred to as a compressed liquid, an interpretation that that is not around to vaporize.
As more heat is transferred, the temperature keeps increasing until it reaches 100°C. At this suggest water is still a liquid, but any kind of heat enhancement will cause some that the fluid to vaporize. A liquid the is about to vaporize is referred to as a saturated liquid.
Once boil starts, the temperature stops rising until the liquid is fully vaporized. Any kind of heat loss native this vapor will reason some the the vapor come condense. A vapor that is about come condense is called a saturated vapor.

If the temperature the the vapor is, let us say, 300°C; and if we deliver some warm from the vapor, the temperature might drop somewhat but no condensation will take location as lengthy as the temperature remains over 100°C (for p = 1 atm). A vapor the is not about to condense (i.e., no a saturated vapor) is dubbed a superheated vapor.
