It depends on the specific gas, liquid, or solid, but in general the index of refraction is higher in solids or liquids than in gases. The speed of light is inversely proportional to the index of refraction.

There is no fixed speed for the transition of a substance from the solid phase to the liquid phase. The maximum speed this can happen at is the speed of light as this is how fast the energy can be transferred to a molecule, and there is no minimum speed. Some substances do not melt into a liquid. Instead they make the transition straight from solid phase into gas phase, and this is called sublimation.
True, the speed of light is faster in a transparent medium like water or glass compared to its speed in a vacuum. This difference in speed is due to the different refractive indexes of the medium, which affects the speed at which light travels through it.
A physical change from solid to liquid state is caused by an increase in temperature, which provides enough energy to overcome the forces holding the solid particles together. This causes the solid particles to gain enough kinetic energy to break free from their fixed positions and move more freely, resulting in the transition to a liquid state.
When a solid changes to a liquid, the particles gain energy and start moving faster, causing the solid to melt into a liquid. So, in this process, the particles speed up.

Light travels faster through liquid than through solid. The speed of light in a medium is determined by the refractive index of the material, which is lower in liquid compared to solid materials.
That could cause a change from solid to liquid, or from liquid to gas.
As the molecules in a body move with increased speed, i.e. increasing kinetic energy, it is possible that the body will change from the solid phase to the liquid phase, or the liquid phase to the gas phase, and in some cases from the solid directly to the gas phase.

When light passes from a liquid to a solid medium, its speed typically decreases, as solids usually have a higher refractive index than liquids. The wavelength of the light wave will also decrease as it enters the denser medium, causing the light to bend towards the normal.
Only one phase change of the four is possible, that of a liquid to a gas. Increased molecular energy is related to dissociative phase changes : solid to liquid / liquid to gas.

When molecules in a body move with increased speed, they gain kinetic energy. If this increase in kinetic energy is significant enough, it can lead to a change in phase, such as from a solid to a liquid, or from a liquid to a gas. These phase changes are a result of the increased movement of molecules overcoming the intermolecular forces holding them together in a particular phase.
The rate of a phase change, such as from solid to liquid, is dependent upon the specific heat of the material, the difference between the solid's core temperature and the room's ambient temperature and the application of any external energy sources such as a light bulb or heating mantle.
