molecules in solids are stationary whilst those in gases and liquids move around, more though in liquid.
Molecules that are in a solid are more confined then those in a gas or liquid state. The atoms themselves are actually moving, but ever so slightly. It's more like a vibration when you think about it. The particles hit/run into each other but they're so close together you can't see the actual movement unlike liquids which move faster than solid particles but slower than gas particles. Just don't go look at a rock hoping to see it's particles moving because it's not something you can see. Just assume it's correct.
Molecules in a solid can barely overcome the attractions between them, so they vibrate in a fixed position (which can be organized or amorphous). Because of this, solids have definite shape and definite volume. The molecules of a liquid can flow over each other but cannot separate from each other, so liquids have a definite volume but no definite shape. The molecules of gases can almost completely separate from one another, so gases have no definite shape or volume.
Molecules in a solid aren't really moving around at all, they're really just vibrating. The molecules in a gas are moving at a very fast speed, faster than a liquid's and a solid's. The molecules are moving at such a fast speed, that they make the material float in a way, that's what makes it a gas.
The molecules of a solid do not have the freedom to move as they would in a liquid or a gas. Solid materials maintain their shape and volume. Liquid materials assume the shape of the vessel in which it is contained and is incompressible. Gaseous materials assume the shape of the vessel in which it is contained and is compressible.
the molecules in a solid are closer together which makes it solid and the molecules in a liquid arent as close together which means they have more room to move around.

Solid- In a solid they are one block of molecules all in an arranged patter
Liquid- In a liquid all the molecules slide past each other
the molecules in a solid are closer together which makes it solid and the molecules in a liquid
Molecules in a solid are more tightly packed than molecules in a liquid.
Liquid to a solid is: freezingLiquid to a gas is: condensationSolid to a liquid : is meltingGas to a liquid is: evaporation
When a substance condenses, it turns from a vapor (gas) into a liquid. When this occurs, the atoms/molecules lose some kinetic energy, and don't move as fast. They also become packed closer together, and take up less volume.
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
there is no particular point which gas changes to liquid, because all substances have different points where gas changes to liquid. Water vapor changes to liquid at 100 degrees Celsius
A gas changing to a liquid is considered "condensation".A most common examples of condensation is the forming of little water droplets on the side of a bottle of water grabbed directly from the refrigerator on a hot day.
Generally, the molecules in gases are further apart than molecules of the same substance in either liquid or solid state. However, note the existence of a critical temperature for each substance. Above the critical temperature, no liquid or solid phase can exist, but it would be theoretically possible to compress a supercritical substance so that it would have closer molecules than some liquid form of the same substance.
the molecules in solids are tigthly packed that is the intermolecular force(cohesive) force is more but in liquids the intermolecular force(cohesive force) is less .solids have fixed shape,volume, mass but liquids have no fixed shape as it takes shape of the container.
the arrangement of it's molecules...... which depend on kinetic energy and intermolecular force.
The molecules will become closer together when becoming a liquid.
they get further apart

A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
The molecules of the substance lose energy and usually assume a fixed lattice shape (which may be a crystalline form or an allotropic form, dependent on temperature and pressure). Some compounds such as glass (various silica compounds) can transition to an amorphous solid (non-crystalline phase) that can be fractured, but also may very slowly flow above a particular temperature (vitrification).
the force of attraction between its molecules becomes strong enough to overcome the energy of motion that its molecules have when the substance is in its liquid state, molecules are locked into rigid crystalline formations.
The velocity of the atoms/molecules (that the substance is made of) increase.
