get you own personal ideas.
hope i can help.

Well that person above was kinda an @$$^^
Anyway My answer would be heat, causing the gas to cool down and become liquid.
From gas to liquid is called condensation. Liquid to solid is freezing or solidification. Solid to gas is sublimation. Gas to solid is deposition. Solid to liquid is melting. Liquid to gas is vaporization.
The additional heat, called "enthalpy" completes the phase change, by changing the arrangement of the molecules in the existing environment, not the temperature. The energy must be removed from a gas to cause condensation into liquid, and from a liquid to cause solidification (freezing). Conversely, it is added when changing a solid to a liquid or a liquid to a gas. At a certain temperature (critical temperature), the process happens spontaneously because the phase boundary disappears.
It affects it so ya Anyways, water becomes black and shines really bright when it is affected to magnesium and cesium bromide
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.
energy is the ability to cause change or do work
Condensation
Physical change can occur when energy is added or removed. For example, adding heat energy can cause water to change from a solid to a liquid (melting), while removing heat energy can cause water to change from a liquid to a solid (freezing). These changes do not alter the chemical composition of the substance.
Thermal (heat) energy must be added or removed in order to cause a change of state.
Water first covert from liquid to gaseous state. It then precipitate as snow(solid) or rain(liquid).
Decreasing the temperature a liquid become a solid.
a phase change from liquid to gas that occurs when water is heated to its boiling point. This process requires energy to break intermolecular bonds and cause the water molecules to transition from a liquid state to a gaseous state.
When liquid oxygen is warmed, it evaporates and turns back into gaseous oxygen. This is because the boiling point of oxygen is -183 degrees Celsius, so any increase in temperature above this point will cause it to change state.
A physical change. Changing H2O from a solid to a liquid or a liquid to gas does not cause any chemical change as in the end you still have H2O.
Cooling a hot substance may result in the condensation of its gaseous state into a liquid state. It may also cause the solidification of a liquid into a solid form as the substance loses its heat energy and transitions to a lower temperature state.
Freezing something?
Freezing something?
a loss in energy cause the change from liquid to solid like-wise a rise in energy causes a change from solid to liquid.
