Change of state happens with the change in temperature and pressure. We can refer below given information for easy understanding:
Solid-heating-forms liquid
liquid-heating- forms gas
gas- compressing(increasing pressure)- can change into liquid as well as solid if applied access pressure
It should also be noted that some gases while compressing change into solid state without changing into liquid and viceversa. Eg. Carbondioxide, Ammonium chloride etc.
This process is called sublimation

How does the oxidation state of 0 change in the following reaction?
The oxidation state of an element with oxidation state 0 cannot change, as it already has a balance of electrons.
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
What has to happen in order for water to change one state to another?
your mom has to happen
What is the difference between a chemical change and a change of state?
A chemical change involves a rearrangement of atoms to form new substances with different chemical properties, while a change of state is a physical change where a substance transitions between its solid, liquid, or gas state without changing its chemical composition.
Is it true or false for A Change In State Is A Physical Change?
True. A change in state, such as from solid to liquid or gas, is a physical change because the substance's chemical composition remains the same and only its physical properties, like shape or state, change.
What has to happen in order for water to change from one state to another?
your mom has to happen
How does change of state take place?
for a state change to happen it must lose or gain or loose kinetic energy
What has happened in order for water to change from one state to another?
your mom has to happen
What happen to energy during a change of state Why is it a physical change?
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
What makes a reaction to happen?
In A Chemical Reaction the following take place a) there is evolution of a gas b) change in colour c) change in state d) change in temperature
How does subliming happen?
Sublimation is a change of state when a solid turns into a gas without going in the process of changing into a liquid.
Is change of state a chemical change?
No, change of state is a physical change.
A change of state is a type of what change?
A change of state is a molecular change.
Is the addition of heat to solid sodium chloride until it melts is a chemical reaction?
Chemical reactions happen on a molecular level Physical reactions are concerned with a change in state or energy level, so melting is considered a physical reaction since there is no molecular change just a change in state.
What has to happen for a chemical change to happen?
At least 2 of the reactants must change their chemical formula.
Is the change of state a chemical or physical chenage?
A change of state is a physical change.
Does the change in state change when glass melts?
Yes, melting is a change of state.
