The particles themselves don't get bigger, they do however start moving more quickly and therefore they use up more space to move around in. (That's why most stuff expands when you heat it)

Do particles get smaller or bigger when heated?
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.
Do gas molecules get bigger when heated?
No, but the spaces between them gets bigger.
What does the particle theory suggest about the motion of the particles of solids-liquids and gases when they are heated?
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
What does the particle theory suggest about the motion of the particles of solids liquids and gases when they are heated?
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
Why do substances often expand when they are heated?
because the particles
When materials are heated they get bigger?
the answer is particles !

When substance is heated its particles expand and increase in size?
it expands and it becomes bigger
Why do particles grow bigger when they are heated?
beacuase the molicules vibrate which makes the heat expand.
How do particles move when they are heated?
Particles move faster when they are heated.
What is bigger gas particles or smoke particles?
smoke particles are bigger than gas particles.
What happens to the particles in a liquid when they are heated?
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
When a substance is heated do the particles get larger?
no they just get more energy and bounce around more and require more space so it seems like they get bigger but they aren't
What happens to the speed of gas when heated?
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
When an solid is heated does it go bigger or smaller?
bigger.
When a substance is heated the particles do what?
accelerate
Particles vibrate faster when they are cooled?
Particles vibrate faster when they are heated.
