A phase change is when matter changes into another form but keeps its properties.
For example, ice melting into water is an example of the phase change melting.
The main types of phase changes are melting, vaporization, freezing and condensation.
- Melting is when a solid turns into a liquid.
- Freezing is when a liquid turns into a solid.
- Vaporization is when a liquid turns into a gas. Boiling is a form of vaporization when the change takes place throughout the liquid. Evaporation is a form of vaporization in which the phase change takes place only at the top of the liquid.
- Condensation is when a gas turns into a liquid.
- There is also sublimation, which is when a solid turns directly into a gas.
- Deposition is when a gas turns directly into a solid.

What reaction of matter will stay the same during a physical change?
The chemical composition of the matter will stay the same during a physical change. Only the physical properties, such as shape, size, or phase, will be altered without affecting the chemical composition of the substance.
Is evaporation of spirit on the skin a physical change?
Yes, evaporation of spirit on the skin is a physical change. It is a phase change where the liquid spirit changes into a gas without any chemical reaction occurring. The process can be reversed by condensation.
Which equation represents a physical change?
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
How do you know when a physical change has taken?
In a physical change, the substance's chemical properties remain the same even though its appearance or state may have changed. Signs of a physical change can include changes in shape, size, or phase (solid, liquid, gas) without altering the chemical composition of the substance.
Is boiling water an example of chemical change?
No, a chemical change is when a substance and forms one or more new substances, it changes its composition. examples: changes in color production of gas formation of precipitate Boiling water is an example of physical change, it can be any phase change.
Is a Chang in a phase a physical change or chemical Chang?
A change in phase is a physical process.
Is a phase change an example of a physical or chemical or nuclear or a covalent change?
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
When icicles form is it a physical or chemical change?
It is called a phase change.
When ethanol condenses and from the gaseous phase into the liquid phase is this a physical change or chemical change?
physical change- the composition of the ethanol is not effected
When boiling take place is the phase change a chemical or physical change?
Boiling is a physical change.
Is soda freezing a chemical change?
No, it's a phase change, which is physical.
If water is boiling is it a chemical change or a physical change?
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
When water changes phase is it chemical or physical?
Physical, as it remains water.
Ice melting is a physical or chemical?
physical because a chemical change means it can never form back
When water is boiled is it a chemical or physical change?
Boiling is a physical phenomenon, a change of phase.
When is a phase change and when is it a sign of a chemical change?
After a physical change the molecule remain intact.After a chemical change the molecule is modified.
