They pop and explote make the gas chemicals to spread...
Particles are spread out to the maximum of the space available.
These particles are transformed in gas.
The motion of particles is accelerated.
vaporizes
Sound is a result of the vibration of the particles of the medium through which it is travelling. The more closely packed the particles are, the faster they bump against the particles next to them.
The gas particles are freely moving because they are not tightly arranged together
The particles of gas speed up.
vaporization
The particles start moving faster and the matter expands.
The particles are no longer fixed by the forces keeping it a liquid
The gas particles are freely moving because they are not tightly arranged together
exerting lots of kinetic energy into gas particles speeds up the collision theory
