water changing to a solid: freezing
movement of particles: vibration in fixed positions.
arrangement: fixed positions (bonds between every particle). moving closer together
water as a liquid:
movement of particles: move about (slide past each other)
arrangement: close together with no regular arrangement
water to gas: boiling
movement of particles: free/random movement at high speeds.
arrangement: particles move further apart with no bonds between particles.
The direction of their motion changes randomly.
No heating something up actually does the opposite, when a substance is heated the particles begin moving faster and this leads to change of state from solid to liquid to gas.
Yes, pressure in the liquid caused by its molecules constantly being in motion force it to take on the shape of its container (within limits).
Any change in motion (direction or speed) is a change in velocity.Velocity is a vector quantity which means that it has a magnitude and a direction.
When a solid melts to become liquid, or a liquid boils to become a gas, the arrangement of particles gets farther apart and less structured, and the motion of the molecules becomes more random and they move faster. The opposite happens when a gas condenses to become a liquid, or when a liquid freezes to become a solid.

As energy is added to a substance, the particles that make up the substance vibrate faster. This is what causes substances to change state (solid to liquid to gas). As the particles move faster, the structure changes.
The direction of their motion changes randomly.
The particles get so attracted to each other making them form into a solid
All particles of all things are in constant motion. Particles in a liquid collide, but the rate is subdued by the viscosity of the liquid.
The substance's state (solid / liquid / gas), density, temperature, etc, is determined by motion and spacing of particles.
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. The closeness, arrangement and motion of the particles in a substance change when it changes state.
No heating something up actually does the opposite, when a substance is heated the particles begin moving faster and this leads to change of state from solid to liquid to gas.

That would be Brownian motion. That refers to small particles (for example, dust particles) suspended in a liquid or gas exhibiting random behavior - this is caused by liquid or gas molecules bumping into the dust particle.
Molecular motion is less constrained in liquid than in solid and is less constrained in gas than in liquid.
