They don't have enough kinetic energy to remain free in the gaseous state.
gas turns into a liquid when cooled because the gas is loosing heat which causes its molecules to form bondswhich bring them closer together to form a liquid. ;)
all liquids turn in to gas at a certain temperature
Condensation. A gas becoming a liquid is condensation. A liquid becoming a solid is freezing. A solid becoming a liquid is melting. A liquid becoming a gas is vapourization. A gas becoming plasma is ionization. A plasma becoming a gas is recombination
a liquid then if cooled further it would turn into a solid a liquid then if cooled further it would turn into a solid
Gas turns to liquid when energy is lost. The density of a gas is much less that the density of a liquid. Thus, when energy is lost and the particles of the gas are able to condense, it becomes a liquid.
Evaporation is the process of water becoming a vapour. Condensation is the cooling of the water vapour back into a liquid.
Condesation
To turn a gas in to a liquid requires cooling or the removal of heat. This process is called liquefaction. Water vapor condenses into a liquid.
It really depends on if it is a science demo or example, or in a business that you are cooling the gas. There may be very logical reasons why they, in which i don't know who you are prefering to, turn natural gas into liquid.
It's called condensation when a gas turns back into a liquid
A gas become a liquid after cooling to the adequate temperature - the condensation point.
The substance could liquefy or solidify. Cooling a gas: change from the gas phase to the liquid phase Cooling a liquid: change from the liquid phase to the solid phase
Cooling water vapor to below 212° F changes the gas to a liquid.
When you heat something, you get to do from solid to liquid, and that called melting. The liquid to a gas its called vaporzation and evaporation. A solid to a gas its called sublimation. When you cool something, you get to do from gas to liquid its called condensation. A liquid to a solid called freezing. A gas turn straight to a solid called deposition.
Normally its a gas, but in a lite neon sign its a plasma.
Condensation. A gas condenses into a liquid.
water vapor (gas state) can turn into water (liquid state) when cooled.
You must either increase the temperature of the liquid or decrease the pressure acting on the liquid (i.e., decrease the air pressure).
