Answer:
i want to say It would be Abecause a chemical change is somthing that cant NOT be brought back to its areganal proproties.coal will never be able to be bavk the way it was!!
Explanation:
because a chemical change is somthing that cant not be brought back to its areganal proproties.coal will never be able to be back the way it was.
Matter exists in different states such as solid, liquid and gas because of the kinetic energy of its particles and the intermolecular force of attraction between the particles.
A substance won't condense into a liquid or solid if the average kinetic energy is higher than the attraction forces holding the particles together.
Thus in solids, intermolecular force of attraction > kinetic energy of particles.
In a liquid (or solid), the average kinetic energy of the particles is low enough to allow the forces of attraction to hold the particles together. In a liquid (or solid), molecules do not separate.
In liquids, intermolecular force of attraction > kinetic energy of particles. But this force of attraction is smaller than solids.
The forces of attraction between the particles in a gas can be overcome by the average kinetic energy of the particles in the gas. When gas molecules collide, they spread apart.
In gas, intermolecular force of attraction < kinetic energy of particles.
