E r u p t i o n or maybe phreatic

A vent is a opening for the relief of gas or liquid pressure.
A gas turning into a liquid is called condensation.
when a gas becomes a liquid, it is called condensation.
The process from a liquid to a gas is called evaporation, where the liquid absorbs heat energy and changes into a gas. On the other hand, the process from a gas to a liquid is called condensation, where the gas loses heat energy and changes into a liquid. Both processes involve a change in temperature or pressure.
Condensation. A gas condenses into a liquid.
evaporation solid to liquid - melting liquid to gas - evaporation gas to liquid - condensation liquid to solid - freezing solid to gas and gas to solid - sublimation
bubbles
When a liquid turns to gas it is called evaporation, vaporization or boiling.
