When a substance undergoes thermal expansion what happens to the particles?

As you might expect from the term "expansion", they get farther apart from each other - at least on average. They also tend to gain more vibrational energy, rotate faster (when able to) and move around faster in general.

What happens when a pure substance undergoes a chemical change?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
What happens to dry ice if it is set out at 45 degrees celsius?
It will explode due to a large Expansion of the particles
What happens to the distance between particles of a substance as it changes from a liquid to a gas?
The distance increases, as the particles become more energetic and the substance loses its definite volume, as the particles bounce around, due to heat/increased energy.
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.
When a substance is heated what happens in mass volume and weight?
Both the mass and weight remain unchanged. However; generally; the volume increases due to the thermal expansion of the substance when heated up.

What process happens when a substance undergoes a chemical change?
A chemical reaction
What happens to particle size when a substance undergoes physical change?
It enlarges

What happens when an unstable nucleus undergoes radioactive decay?
Particles or electromagnetic radiation are emitted.
What happens to the particles when the substance changes shape?
yes! particles of a substance assume different shapes and sizes
What happens to particles when boiled?
Boiling occurs when the intermolecular forces holding a substance in the liquid state become overwhelmed and allow the particles to separate into the gaseous state. Particles in the gaseous state are roughly 2000 times farther apart than in the liquid state, which causes expansion of the substance in its gaseous form.
What happens to matter and the particles of an object during physical change?
The particles are affecting the form of a chemical substance and not turning into a new substance.
What happens when to particles of a substance when it condenses?
Particle Movement decreases.
What happens to the particles in a solid when it is heated but not melted or burned?
Thermal expansion occured.
What happens to the temperature of a solid when it is heated?
Heat affects the properties by speeding up the particles and providng them with more energy. As they heated the bounce off one another and expand the solid. When it's cold, The particles have less energy and don't move as much, This results in contraction and the solid shrinks. Basically, Heat ---> expansion Cooling -----> contraction
