gas to a liquid
from a solid to gas
Phase change.
The state of matter that shows the largest change in volume when warmed or cooled is gas. Liquids and solids increase and decrease in volume in response to temperature change as well, but not to the same magnitude as gases.
There are three main states that a substance can exist as: solid, liquid and gas. The transition between these states occur when a substance is heated or cooled past their freezing/melting or boiling/condensing points. Solid -> Liquid = Melting Liquid -> Gas = Boiling Gas -> Liquid = Condensing Liquid -> Solid = Freezing
Then the physical characteristic of a substance change, it is called a change in state. This most commonly occurs when a substance is heated or cooled. The states that substances are solid, liquid and gas. A common example would be water: ice (solid), water (liquid), and steam (gas).
When a substance is cooled, its molecules slow down and have less energy, causing them to move closer together. This often results in the substance contracting or becoming more dense. In some cases, cooling a substance may also lead to a change in state, such as from a gas to a liquid or from a liquid to a solid.
One way to change the state of a substance is through heating or cooling it, which can lead to melting, freezing, evaporation, or condensation. Another way is applying pressure, which can cause a substance to change from a solid to a liquid or a liquid to a gas.
Water is a substance that changes from a gas (water vapor) to a liquid (water) through a process called condensation. This change in state occurs when the temperature of the water vapor decreases, causing it to lose energy and form liquid water droplets.
gas to a liquid
When cooled enough it will condense into a liquid. The required temperature changes with the substance.
The phase change in which a substance changes from a gas to a liquid is called condensation. It occurs when the temperature of the gas decreases to reach its condensation point, causing the gas molecules to come together and form a liquid.
The energy needed to change a substance from a liquid to a gas is called heat of vaporization.
The chemical identity of a substance remains the same when it turns into a gas. The type of atoms and their arrangement within the substance do not change during the phase transition from liquid to gas.
It is condensation.
