gas phase
Heat is needed for matter to change form eg: Melting, condensation, etc.
Phase changes occur when a substance transitions between different states of matter, such as solid, liquid, or gas. Factors that influence these transitions include temperature, pressure, and the intermolecular forces between particles. When these factors change, the arrangement and movement of particles in the substance can also change, leading to a phase change.
To change phases of matter, you need to either add or remove energy. Increasing energy input causes a substance to change from solid to liquid to gas (melting, vaporization), while decreasing energy input causes the reverse phase changes (condensation, freezing). The temperature and pressure of the substance also play a role in determining its phase.
I am pretty sure that it is the temperature which is applied to the substance. For example when heat is applied to a solid it melts, causing it to change from one phase to another. Also when a liquid freezes the temperature drops and it converts into a solid.
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
The change in pressure is highly affected by altitude.

This is called a change in phase or a phase transition. It occurs when a substance transitions from one of the states of matter (solid, liquid, gas) to another due to changes in temperature or pressure.
A combination of varying pressure and/or temperature.
The state of matter can be changed by altering the temperature or pressure of a substance. For example, increasing the temperature of a solid can cause it to melt and change into a liquid, while lowering the temperature of a gas can cause it to condense into a liquid. Similarly, changing the pressure can also affect the state of matter.
Change of phase is caused 99% of the time by a change in temperature or pressure.

Phase change. Liquid phase to gaseous phase (evaporation) Liquid phase to solid phase (solidification, freezing) Solid phase to gaseous phase (sublimation9 Etc...
Any type of reaction, really. You could add heat or remove heat (thermal energy) to cause the matter to change phase. Also pressure can compress the matter into a new form.
Changing the temperature or pressure of a material we can change the phase.
In physics, the solid to liquid process is known as melting. The three states of matter are solid, liquid, and gas. There is a change in phase or a phase transition in a substance when there is a change in either its temperature or pressure. The melting process is a phase transition.
The variables responsible for the three phases of matter are temperature and pressure. In general, increasing temperature tends to transition matter from solid to liquid to gas, while increasing pressure can have the opposite effect. These variables influence the arrangement and movement of particles in a substance, leading to the different phases.
