The movement of the molecules making up the solid increases.
if volume of a gas increases temperature also increases
Kinetic energy is possessed by virtue of the motion of particles. In solids, particles are tightly packed, so the can not move easily(hence the rigidity). In gases, particles are loosely packed, so they can move more freely(hence its ability to flow). Therefore, KE of particles increases when a solid changes to gas.
When a solid changes to a liquid, it melts and gains more kinetic energy. When a liquid changes to a gas, it evaporates and gains even more kinetic energy. When a solid changes directly to a gas without passing through the liquid state, it is known as sublimation.
When a gas changes directly to a solid it is known as deposition.
When a solid changes to a gas adjustments in its state appear. Atoms move from been solidly arranged to make it stiff to atoms moving around freely and the gas can occupy the areas around the atoms.
When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
Condensation happens when a gas or a vapor changes into a liquid or a solid. H2O (v) ----->H2O (l or s) V= vapor L=liquid S=solid
It sublimes

These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
The phase changes of matter are melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid). These transitions occur due to changes in temperature and pressure.

The difference is that evaporation happens on the surface of the liquid, and boiling happens throughout.)gas to liquid= condensationgas to solid= depositionsolid to gas= sublimation
