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.

Why is kinetic energy of liquids more than solids?
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.
Do Solids usually conduct heat better then liquids and gases?
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.
Do liquids have higher density than solids?
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.
Why are hydrogen and helium within the giant planets largely in liquid state?
Inside the gas giants of our solar system hydrogen and helium and other gases are liquids and solids not because of cold temperatures but because of the monumental pressure within the planet.
What are some of the general properties of gases that distinguish them from liquids and solids?
Some properties or characteristics that distinguish gases from solids and liquids are that they are compressible and also can expand to fill the volume in a container. Likewise, gas molecules are far apart and can occupy more space when compared to those of solids or liquids.
What are the movement of particles within solids liquids and gasses?
diffusion.

Do mechanical waves travel faster in solids or liquids?
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. :)
Why are liquids liquids?
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.

How do solid become liquid?
Liquids become solids by cooling. For example pure water upon cooling to 0 Degrees Celcius will turn from a liquid state to a solid state. Cooling / freezing slowing down or restricts the movements the particles within the substance and as this occurs they move slower and slower till they obtain a near stationary state, known as a solid.
Do the particles in solids move?
Particles within are limited to vibrational motion, unlike the particles which make up liquids which can have vibrational & translational motion, and gaseous particles which have vibrational, translational and rotational motion.
Which substance will most likely not quantitatively follow Henry law dissolved in water?
Henry's law - the relationship between pressure and the solubility of a gas within a liquid. The solubilities of solids and liquids are not affected by pressure.
Two types of movements within the alimentary canal?
mixing movements and propelling movements
