In case of solids only free electrons namely outermost electrons are capable of moving freely through solids. The ions are held in the crystal structure and they are just vibrating about their mean positions.
But in case of fluids namely liquid and gases, the molecules or atoms as a whole are free to move at random. Sometimes they may get ionized and these ions would move at random.
The kinetic energy in liquids is greater than that in solids because the molecules in solids are more closely packed together than in liquids such that liquids can freely move about within the containing vessel.
Solids do conduct heat better than gases, although not necessarily better than liquids. Some solids are actually composite materials, because they can have a porous structure which contains gas within the solid, and this results in solids that do not conduct heat very well. But it is the gas component which has this insulating property.
Yes, water is one of the exceptions to the rule that a solid shrinks when it solidifies. Water expands. If you freeze water in glass eg beer bottles, the bottle will shatter as the liquid freezes. Water pipes can burst, metal water bottles will split if frozen full of water. The water takes in air as it freezes, thus ice floats in your glass rather than sinking.
In a black hole, all matter and energy that crosses the event horizon gets sucked in due to the immense gravitational pull. This includes light, particles, and even information, which becomes trapped within the black hole's singularity at the center.
Liquids are fluids so they flow, and they are able to move around and over each other. Liquids have a definite volume but no definite shape and they will find their own level within a container.
diffusion.
Mechanical waves involve the physical transfer of vibration from one particle to another within the medium. Denser materials (solids and liquids), have closer particles so this transfer of energy occurs more quickly. :)

No. The particles in the solids have different mass as the particles in the liqiuds, so they diffuse at the different rate. but if their particles have the same rate, they will diffuse at the same rate.
The answer of this question is similar to the questions why solids are solid and gases are gas? The answer is that in solids the intermolecular forces between the atoms of solid is very strong and they bound each other very strongly. The atoms of the solid can't move here and there and they have definite shape and called solids. Similarly gasses are those in which intermolecular forces are very week and the atoms can't held each other strongly and that's why the atoms separated randomly and they called gasses. As liquid is the intermediate state between solid and gas similar to this the intermolecular forces among the atoms of the liquid is less than solid but more than gasses. Due to such kind of forces liquid neither get a definite shape nor the atoms separated but the atoms can move within a definite area and can squire any shape and that's why they are called liquid.

Liquids change into solids through a process called solidification or freezing. When liquids are cooled below their freezing point, the particles within the liquid slow down and the attractive forces between them cause them to arrange into a more ordered structure, forming a solid.

move and transfer heat through bulk motion like gases and liquids. Heat conduction is the primary mode of heat transfer in solids, where energy is transferred through the vibration and collision of atoms and molecules within the solid material.
If you are talking about solids liquids and gasses, then it depends on how fast the molecules are moving. in solids, they vibrate in place. In liquids they slide past one another. In gases the bounce. In plasma the bounce with either a positive or negative charge.

Sound can travel through solids, liquids, and gases. In solids, sound travels the fastest due to the close arrangement of particles. In liquids, sound travels at a medium speed, while in gases, it travels slower as the particles are more spread out.
