Energy content of the molecules of gas decreases. Energy of the system remains same.
But it depends on what the conditions are too. Depends on the process of conversion:
If it's isobaric, then decreases
If it's isochoric, then decreases
If it's isothermal, then increases
If it's adiabatic, then no change

What can happen when the average energy of a liquid's particles decrease?
Either and both liquifaction &/or freezing.
If a substance undergoes a phase change what happens?
When a substance undergoes a phase change the molecules either order themselves or disperse themselves randomly. In a solid the molecules are unable to freely move in space. In liquid form they are able to move around in the space they occupy and in gas form they can move freely in any open area. In gas state the molecules will have more kinetic energy than liquid or solid, and liquid more than solid.
How do you change water into water vapour?
By heating the water. Boiling it, which would turn it into steam (a gas). The process of changing liquid water into a gas is called evaporation. Energy is added to the liquid water - generally in the form of heat. When enough energy is added, it allows the most energetic molecules at the surface of the liquid to break free of the liquid and enter the gas phase. The more energy that is added, the more water molecules will have enough energy to move into the gas phase. If enough energy is added, all the molecules will leave the liquid and from then on adding energy will just make the gas warmer. Another way to change liquid water into gas is to drop the pressure above the liquid. In this case, it takes less energy for the molecules in the liquid to get away from the liquid so some of them will already be energetic enough to get away.
Why cant you change temperature and phase at the same time?
When an object is changing state form liquid to a gas the object is absorbing energy to allow its molecules to expand. it cant increase in temperature because it is using the energy that it is absorbing. When an object is changing state form liquid to a gas the object is absorbing energy to allow its molecules to expand. it cant increase in temperature because it is using the energy that it is absorbing.
When soil becomes more liquid it becomes what?
mud
When an obeject is changing from a liquid to a solid does the energy increase or decrease?
The energy level decreases.
Does kinetic energy increase or decrease when a liquid changes to a gas?
the kinetic energy increases
What happens when liquid releases energy?
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
What happens to a liquid when it release enough energy?
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
What happens to a liquid when it released enough energy?
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
