solidity
The physical state that cannot exist in a solution is solid. This can be either liquid or gaseous states but not in solid form.
Atoms cannot exist in a free state on their own, but can exist in a free state as molecules.
There are several physical forms in which a substance can exist. The common ones on earth are solid, liquid and gas, although some substances cannot exist as all three.A solid, liquid, gas or plasma.
State
A solution does not have a chemical change, but it does have a physical change in state.
evaporation
It's an aqueous solution.
physical state defines the shape size and the form in which the matter exist in nature
It's an aqueous solution.
State
Elements do not change when moving in between the 3 physical states. A physical transition cannot change what the element is, only what state it exists in. A chemical change is where two elements combine together to form a different product than you started with. The only way to change what an element is, is to add or subtract protons.
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
