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 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.
Are filtering air to remove dust and pollen a physical and chemical change?
Filtering air to remove dust and pollen is a physical change. This is because the process does not alter the chemical composition of the air or the dust/pollen particles. Instead, it simply separates the particles based on their physical properties.
Is filtering air to remove dust and pollen a physical or chemical change?
Filtering air to remove dust and pollen is a physical change because the process does not alter the chemical composition of the dust and pollen particles. It simply separates them from the air through physical means, such as using a filter.
Is sedimentation a physical change or a chemical change?
Sedimentation is a physical change. It involves the settling of solid particles due to gravity and does not involve any change in the chemical composition of the substances involved.
Is stirring a chemical change?
No, stirring is a physical change. It does not alter the chemical composition or create new substances; it only affects the physical state or distribution of particles within a mixture.
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 kind of change happens when a brick crumbles Physical or chemical?
It is a physical change.

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 crushing limestones into smaller particles a chemical change?
No. It is a physical or mechanical change.
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 a chemical change happens, a physical property is change. A physical property something that you could use to describe something or someone with your senses.

What happens with the sulfuric acid and is it a chemical change or physical change?
The chemical reactions of sulfuric acid are chemical changes.
Is sedimentation a physical change or a chemical change?
Sedimentation is a physical change. It involves the settling of solid particles due to gravity and does not involve any change in the chemical composition of the substances involved.
Frying an egg physical or chemical?
It is a chemical change because it is irreversible and the change happens on a molecular level.
Is the ability to dissolve a physical or chemical change?
Dissolving is a physical change because it does not alter the chemical properties of the substance being dissolved. It involves the separation of particles within a substance without changing their chemical composition.
