When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
In general, particles do not get bigger when they are heated. When particles are heated, they gain energy and move faster, which may cause materials to expand due to thermal expansion. However, the individual particles themselves do not increase in size.
the particles within the solid, liquid or gas vibrate to spread around the heat energy, however you cannot tell they are vibrating, it just feels warmer, this works best in metals as they have free moving electrons.
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
Thermal expansion is when something gets bigger (expands) as it gets hotter and smaller (contracts) as it gets colder. This happens because the particles inside the object move faster and spread out when heated, causing the object to expand. This phenomenon is why bridges have gaps and train tracks have small spaces between the rails.
As particles become heated, they expand and grow larger.
the answer is particles !
bigger.
When a material is heated, the particles within the material gain energy and vibrate more rapidly. This increased movement causes the particles to push farther apart, which can result in the material expanding or getting bigger.

Colloid particles are smaller than suspensions particles.
It gets bigger
it expands and it becomes bigger
particle is a general term. subatomic particles are smaller than atoms. dirt particles, for example, are much bigger than atoms
The bigger the particle the higher the infiltration rate is.

beacuase the molicules vibrate which makes the heat expand.
