By definition, a particle is a solid, so your question does not make sense.
Particles are spread out to the maximum of the space available.
vaporizes
When a gas is heated, the kinetic energy of the gas particles increases. This causes the particles to move faster and farther apart, leading to an increase in pressure and volume. Heating a gas also increases the average speed of the gas particles.
The gas particles are freely moving because they are not tightly arranged together
vaporization
They pop and explote make the gas chemicals to spread...
The particles are no longer fixed by the forces keeping it a liquid
The particles start moving faster and the matter expands.
is move themselves
The gas particles are freely moving because they are not tightly arranged together
The average particle speed increases.
When a gas turns into a liquid, its called condensation. The particles slow down and move closer together.
