What happens to the particles when a physical or chemical change occurs?

As a substance goes from the solid to liquid to gas state, the particles in it are getting farther and farther apart, because they are obtaining more energy, causing them to move around faster, collide more, and move apart. As a substance goes from the gas to liquid to solid state, the particles in it are getting closer and closer, because they are losing energy which causes them to slow down and get pushed tighter together.

What happens to particles when they are dissolved?
There is a change in the physical properties of these particles. Their chemical formula remains intact.
What happens to the particles of matter during a chemical change?
it will change to liquid
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.
What is a sidewalk warmed by the heat of the sun a chemical or physical change?
It undergoes a physical change because the matter that makes up the sidewalk does not change. THe side walk goes through a chemical and physical change because the heat makes it constrict by shacking the particles just like it happens with food

How does chemical change happens in photosynthesis?
it happens when •A physical change is reversible, a chemical change is not.•the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't.

What happens in a chemical change but not in a physical?
Molecules permanently change. In a physical change the effects are reversible.
What happens when a chemical change take place?

When food coloring is added to water is that a chemical or a physical change?
Physical because we can still seperate the particles
