Chemical. When a solute, let's say salt, dissolves in water the Chlorine and Sodium atoms in the salt molecules dissociate. They then wander around in the water as negative and positive ions respectively. Even thought the salt is now part of a liquid solution, it's still in solid form because it doesn't contain enough heat to act freely like a liquid. This is evidenced when saltwater is boiled and all the water vaporizes, but salt crystals form at the bottom of the container.

Is steam a chemical raection?
NO!!!! It is a physical change of water from liquid to gas(vapour).
What is always a characteristic of a chemical change but not always a characteristic of a physical change?
When a chemical change takes place, the chemical structure of particles involved changes (i.e. one or more new substances are formed). In a physical change, the physical state of the particles involved changes (e.g. a solid melts and becomes a liquid). The chemical structure of the particles does not change, and no new substance is formed.
Is a liquid at normal temperatures and pressures a physical or chemical change?
This liquid is only a liquid, not a change.
Is Melted Wax A Chemical Change chemical Property?
It is physical change. It is a physical property. There is no change in the composition of the was as it becomes liquid.
Is chlorine gas becoming a liquid a physical or chemical change?
It is a physical change because the chemical composition has not changed.
Is pouring liquid a chemical change or physical?
A physical change.
Is steam a chemical raection?
NO!!!! It is a physical change of water from liquid to gas(vapour).
Is the melting of ice a physical change or a chemical change?
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
What is always a characteristic of a chemical change but not always a characteristic of a physical change?
When a chemical change takes place, the chemical structure of particles involved changes (i.e. one or more new substances are formed). In a physical change, the physical state of the particles involved changes (e.g. a solid melts and becomes a liquid).

Is condense e a physical change or chemical change?
Condensation is a physical change, as no new substances are being formed. It is only water changing from gas form to liquid form.
Is changing liquid to gas a chemical change or physical change?
physical change
Is liquid to a gas chemical or physical change?
it is a change of state, a physical change.
Is dissolution of a solid in a liquid physical or chemical change?
a physical change
Is liquid to gas chemical change?
No, it is physical change.
When a liquid is expanded by heat is that a chemical of physical change?
It is a physical change because the chemical composition of the substance does not change.
Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
What is the difference between Chemical vs physical change?
A physical change is when something changes to a different state (solid, liquid or gas), but it does not change chemical composition; for example, it remains H2O. In a chemical change, new chemical bonds are formed.
