What must happen to water in the liquid phases for it to become water in the gaseous phase?
The hydrogen bonds between Hydrogens of one water molecule and the oxygen of another water molecule must break. These are not actual bonds but they are interactions of the dipole moments produced by the difference in electronegativity between the hydrogen and oxygen atoms in a single water molecule.
When enough heat or drop in pressure is produced the molecules will dissociate from one another and enter a vapor phase.

When is a substance in the gaseous phase called a vapor?
A substance is called a vapor when it is in the gaseous phase at a temperature below its critical temperature. Above this critical temperature, the substance is in the supercritical fluid phase rather than a distinct gas and vapor phases.
Wax like all matter comes in many phases. What are the three possible phases?
gas soild lique
What phases are in equilibrium at a substance's melting point?
Evaporating and condensing
What is a substance's critical point?
A substance's critical point is the temperature and pressure at which the gas and liquid phases of the substance become indistinguishable, forming a supercritical fluid. At the critical point, the substance exhibits unique properties, such as density and viscosity, that differ from those of its gas or liquid phases.
What is the temperature at which vapor pressures of solid and liquid phases are the same?
The temperature at which the vapor pressures of the solid and liquid phases are equal is called the triple point. At the triple point, all three phases (solid, liquid, and gas) can coexist in thermal equilibrium.
Can ice and boiling water exist at same temperature?
Yes. In fact, there is a specific combination of pressure and temperature where the solid, liquid, and gaseous phases can co-exist. Do some reading on "triple point".Yes.

Where can you identify the different phases of water?
You can identify the different phases of water in its solid form as ice, liquid form as water, and gaseous form as water vapor.
What does phase mean in chemistry?
a mechanically separate, homogeneous part of a heterogeneous system or the solid, liquid, and gaseous phases of a system.
Is vapor included in the phases of matter?
Yes, Vapor is a phase of matter between liquid and plasma. It is generally referred to as the gaseous phase.
What is a item that has all 3 phases of matter present?
It's water because it's first a liquid then you can change it into ice which is solid then you can melt it which becomes a liquid . After you can put the liquid in a boiler. When it gets hot the steam comes out which is normally gives off gas
What is the temperature at which a liquid and gaseous phases are in equilibrium?
The temperature at which a liquid and gas are in equilibrium is called the boiling point. At this temperature, the vapor pressure of the liquid equals the atmospheric pressure, allowing the liquid to change into gas and vice versa at a constant rate.
What is a phase in science term?
Phases are defined as distinct periods or changes during the development of a person or animal. Phases are also defined as carrying something out in stages.
How does density vary for a component at its critical point?
For a pure component the density difference between a liquid and gas approaches zero as the critical point is approached. By definition liquid and gaseous phases are indistinguishable (meaning no difference) at the critical point.
The triple point of a substance is the temperature and pressure conditions at which?
the solid, liquid, and gas phases of a substance coexist in equilibrium. At the triple point, the substance can exist in all three states simultaneously. It is a unique combination of temperature and pressure for each substance.
What are the liquid phases?
solid liquid and gas
Compare the densities of the soiled liquid and gaseous states of an substance?
As a rule of thumb ... which is not true in all cases ... the solid and liquid states will have similar densities with the liquid being the less dense of the two, and the density of the gas will be much lower.Near the critical point the density of the liquid and gas phases will be nearly identical.
Why is it not proper to regard gaseous state of ammonia as vapours?
Gaseous ammonia should not be regarded as vapors because "vapors" typically refer to the gaseous phase of a substance that is normally a liquid or solid at room temperature and pressure, and is in equilibrium with its condensed phases. Ammonia, however, exists as a gas at room temperature and pressure, meaning it is not in equilibrium with a liquid or solid phase under those conditions. Therefore, ammonia's gaseous state is considered a true gas rather than a vapor.
