chemical change
When a substance loses energy, it becomes more compact. A gas would turn to liquid and a liquid would turn to solid.
Transmutation.
It is a physical change because the boiling water will turn into steam (process called gas), and in reverse it will turn into water again (process called condensation). It will be the same substance all the time
True because when you mix chloride and sodium you get a chemical change, which in turn creates a new substance.

Chemical reactions turn chemicals called reactants into chemicals called products.
The particles emitted by a radioactive substance can change other atoms, and in some cases, they will turn into radioactive isotopes.
Shifting temperature. If its colder, the harder it will get because the particles will compress together. If its warmer, the substance will liquify (melt) or even turn into gas because the particles move apart from each other.
a liquid then if cooled further it would turn into a solid a liquid then if cooled further it would turn into a solid
Sodium hydroxide or any other Alkaline substance an alkiline is a corrosive substance that turns litmus blue ;)
This change is called vaporization.
Substance abuse or mental illness among other reasons.
