Particles Are in constant motion, in a solid they vibrate in place. The only reason the solid and liquid states exist are because of intermolecular forces. These forces are what keep particles together without chemical bonds. When a solid is heated, the particles will vibrate more violently and eventually break apart and become liquid or gas once a high enough temperature is reached. This is because the IM forces are not enough to keep the molecules or atoms together once a certain temperature is reached. The atoms move too fast to stay together once the melting point is reached, causing them to flow, but once the boiling point is reached, atoms move so fast that they break away completely and diffuse freely. So yes the particles will move once a certain temperature is reached, but the particles were already moving in thee first place. Only at absolute zero temperature will the particles be still..at this point scientists have not been able to bring anything to absolute zero, probably because to observe something, you must blast energy, or light, at it. They can get extremely close, within a few or fractions of degrees, but never absolute zero.

How do particles move when they are heated?
Particles move faster when they are heated.
What happens to the particles of a crystalline solid as it is heated at its melting point?
The particles start to move randomly as the process of the liquid starts to form. So during the transformation the bond between the particles start to move. The particles begin to move randomly, and then the crystalline forms a liquid. The faster the particles move the more it transforms into a liquid.
What happens to the particles in a solid when the solid melts?
The atoms start to move around more quickly and when the solid reaches it's melting point it will turn into a liquid.
Are the particles in a solid free to move?
No. According to the Kinetic Particle Theory, the particles in a solid are fixed very close together in fixed positions. They are not free to move and can only vibrate about their fixed positions, due to the strong attractive forces between them. This explains why solids have fixed shapes.
What does a solid do when you add heat to it?
The solid changes state and becomes a liquid because the particles are heated, therefore needing mor room.
Why does a solid expands on heating?
The particles in a solid, move very little. But when it is heated, the particles expand because the heat moves the particles around more, making them need more space to move, therefore expanding the solid. =)

How do particles move when they are heated?
Particles move faster when they are heated.
Can solid particles move?
solid particles cannot move.
What happens to particles in a substance when its heated or cooled?
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
How do particles of a solid move?
If the object is completely solid the particles don't move

The particles begin to move randomly, and then the crystalline forms a liquid. The faster the particles move the more it transforms into a liquid.
Do gas particles move slower than solid particles?
No. Gas particles move much faster than solid particles.
What happens to the particles in a solid when the solid melts?
The atoms start to move around more quickly and when the solid reaches it's melting point it will turn into a liquid.
What are the three things that occur when particles of a solid are heated until it melts?
The bonds between solid particles are weakened.
Do particles in a solid move faster than particles in liquid?
No, particles in a solid only vibrate, whereas particles in a liquid are free to move within the liquid.
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.
