Why is energy needed to change liquid into a gas?
To change a solid into a liquid, or a liquid into a gas, requires heat energy. This heat energy allows the change of state to happen, and the temperature remains constant during the process.
What must occur for a liquid to change into gas?
Vaporization. If the water is hot enough, it starts to boil. Bubbles of water vapor are formed in the boiling water. This happens as particles of liquid water gain enough energy to completely overcome the force of attraction between them and change to the gaseous state.
How do you change a liquid into a gas?
- alcohol in water
- , vinegar (acetic acid in water)
- acetone & oil
What gases can be changed into a liquid?
Such as water, alcohols, ethers, Iodine, octane, etc. COnversely most common gasses exits as a liquid is the pressure is increase and/or the temperture is reduced. Examples include Nitrogen, Oxygen, Flourine, Chlorine, Carbon dioxide, Nitrous Oxide, Propane, ethane, ethyne (Actyline), Butane, etc.
How does water changes from gas to liquid?
Once water vapor is in the atmosphere, low temperatures cause the vapor to either condense into a liquid or undergo deposition to form ice crystals. Water droplets and ice crystals in the atmosphere form clouds, which are moved around the planet by air currents.

What happens when a gas changed to a liquid?
When a gas changes into a liquid, it is called condensation. When a liquid changes into a solid, it is called solidification. When a gas changes into a solid, it is called deposition . When a liquid changes into gas, it is called evaporation.
What is a gas to liquid called?
Condensation - gas to liquid. If a gas is cooled, its particles will eventually stop moving about so fast and form a liquid. This is called condensation and occurs at the same temperature as boiling.
How does a gas become a solid?
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
Is the phase change from gas to liquid exothermic or endothermic?
Thus any transition from a more ordered to a less ordered state (solid to liquid, liquid to gas, or solid to gas) requires an input of energy; it is endothermic. Conversely, any transition from a less ordered to a more ordered state (liquid to solid, gas to liquid, or gas to solid) releases energy; it is exothermic.
Is liquid to gas a physical change?
Physical changes that involve a change of state are all reversible. Other changes of state include vaporization (liquid to gas), freezing (liquid to solid), and condensation (gas to liquid). Dissolving is also a reversible physical change.
What are the 5 phase changes?
Sublimation, deposition, condensation, evaporation, freezing, and melting represent phase changes of matter.
