When a liquid and its vapor are at equilibrium and pressure is suddenly decreased cooling occurs why?

Since the volume did not change, then a decrease in pressure has to change the temperature as well. The change in pressure decreased the kinetic motion and energy of the molecules, so the temperature correspondingly drops. This follows Gay-Lussac's Law where P1T2=P2T1

What is non equilibrium cooling?
For binary alloy cooling, the cooling temperation is a range instead of a fixed line. During the transition (the range), equilibrium of two metals take place at each temperature (temp. decreasing), if the equilibrium finished before going to lower temperature , this is equilibrium cooling. If not, this is the one with the word "non". Check more about binary eutectic system. Just trying to answer.
What it the effect of non-equilibrium cooling on solid state phase tranformation in metals and alloys?
Basically there are two types of effects that may happen during this non-equilibrium cooling. 1. Micro-segregation -result in "hot shortness" which means the material will melt below the temperature of equilibrium solids. -this can be fixed by homogenization heat treatment, heat and hold material to allow diffusion to even out the composition gradients. 2. Macro-segregation -composition gradients on scale of part because some locations solidify before other location in part. -this situation can only be removed by mechanical mixing, in other words hot work or cold work Hope this helps
What is it called when the air temperature drops because of it rising?
Adiabatic cooling is cooling as a result of reduced air pressure(i.e. rising air)
Will carbon dioxide in a carbonated soft drink dissolve best after shaking the container or after heating the container or after cooling the container or after releasing the pressure?
After cooling the container
Most of earth's cloudiness can be said to result from?
Most of the cloudiness on earth is a result of adiabatic cooling. This type of cooling is when heat is reduced when there is a change in air pressure.
Name at least two ways that thermal energy in air can be decreased?
The thermal energy in air could be decreased by cooling it by contact with a chill plate; or if the air pressure were decreased, the frequency of collision would decrease.

What are the two main reasons that air on earth moves?
We have dynamic equilibrium in our atmosphere where pressure systems (high & low) induce the movement of air so that these pressures are continuously being balanced. Heating air causes it to rise, & as result, cold air will rush in to reaffirm equilibrium. The place where the cold air ruhes to forms a high pressure system & the place that it rushes out of forms a low pressure system. The converse is true for the cooling of air.
If a solid object radiates more energy than it absorbs, its?
Cooling down and as such not in thermal equilibrium.
Where is coolant pressure release valve for a 2004 dodge caravan?
The radiator cap controls cooling system pressure.The radiator cap controls cooling system pressure.
What is the benefit of having pressure on a cooling system?
Pressure on a cooling system raises the boiling point of the liquid and aids in the efficiency of the system.
What does cooling form?
a high pressure area
Why radiator get dry?
There is a leak somewhere in the cooling system. Have the cooling system pressure tested for leaks.
How do you do a pressure test on a 1999 Sunfire?
Pressure test ?? Cooling system? A/C? Fuel Pressure? Compression?
What would cause too much pressure building up in the cooling system?
The usual cause of cooling system pressure surges is a bad head gasket. The compression from the cylinders gets into the cooling system and raises the pressure. Have a mechanic run a compression test to see if there are any big pressure changes between the cylinders.
