States of matter are determined by the amount of Kinetic Energy they have. When a gas becomes a liquid, it loses energy, and the particles slow down enough to affect each other. This is why liquids have a volume.
The atoms sperd apart futher due to the energy of the heat making the particles move more/faster.
The parcticles are no longer held by an attraction.
>it changes shape and volume <
The chemical nature remain unchanged.
what occurs when liquid becomes a gas?
boiling
evaporation
Evaporation
yes
No; this process is called evaporation.
freezing
its surface tension
These particles are transformed in gas.
Evaporation (more for talking about water) or vaporization (as a general term) refers to the process in which a liquid changes into a gas. In evaporation, the liquid turns into a gas at the surface. In boiling, vaporization occurs throughout the liquid.
That would be evaporation; the particles inside the liquid escape from the surface and into the atmosphere/air.

This process is called evaporation.
In a liquid state, particles are moving at many different speeds. At the surface of the liquid, some of the faster-moving particles are able to escape into the air. Slower-moving particles stay in the liquid state. Slower motion means lower average energy, however, and this means lower temperature. As high-energy particles leave the surface of a liquid it then cools the surface on which it is resting. Scientist call this phenomenon evaporative cooling. Evaporating cooling is common and can be very useful.
Surface tension-Attractive forces cause particles on the surface of a liquid to pull together and resist from being pushed apart. These particles on the surface are pulled toward the center of the liquid and and sideways along the surface. There are no liquid particles above to pull on them. Particles under the surface are pulled in all different directions. Surface tension is the uneven forces acting on the surface particles of a liquid. Surface tension causes a liquid to act like it has a thin film stretched across the surface.
freezing
When the particles of a liquid gain energy some of them can escape from the surface, and if eventually all of them do this a gas will form. We call this evaporation. If there is sufficient energy for all of them to escape at once, they all move to be far apart and we say the liquid boils.
