individual particles do not expand, when a substance expands it is the dead space between the particles that expands and the particles begin to move around (assuming the substance was solid to begin with).
If a particle did expand it would loose cohesion and break apart (possibly creating an atomic reaction depending on how it was expanded)

If you add heat energy to a substance what happens to the speed of the particle motion?
The particle speed increases.The energy increases; the speed increases.
What happens when thermal energy is absorbed by a substance?
When thermal energy is absorbed the substance expands to some extent that is if it is a ball it becomes oblated to a very small extent as a balloon expands on blown with air , if it is a lengthy object the length becomes little longer.
When a substance freezes what happens to the mass?
Nothing. The amount of atoms stay the same. Usually, though, the volume decreases. However, when water becomes ice, it expands.
What happens to water as it frezzes?
It expands.
What happens to your chest when you breathe in?

What happens when to particles of a substance when it condenses?
Particle Movement decreases.
What happens to particle size when a substance undergoes physical change?
It enlarges
If you add heat energy to a substance what happens to the speed of the particle motion?
The particle speed increases.The energy increases; the speed increases.
What happens to particle of sugar when they melt and dissolve?
When a substance dissolves in water, water molecules get between the particles of the dissolved substance, separating them.
What is the smallest particle a substance?
An atom is the smallest particle of a substance.

When a substance is heated it can result to a rise in?
Electricity and volume This happens because when the mass expands over heat the density expands which in turn makes the volume expand
What happens when railway tracks get hot?
railways expand on hot day because the particle are moving faster, which makes it need more space so it expands:)
What substance expands when frozen?
water
