Movement requires energy.
If an object moves, it has kinetic energy. The same applies to particles.
When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. The change in temperature depends on the number of particles affected.
Well it does. Every substance in any phase, consists of particles that are in constant movement. Sometimes it is a mere oscillation of particles, but sometimes particles move freely. In liquid the majority of particles move around each other, but forces between them, which can be called bonds sometimes, are preventing them from moving around very far.
The link is that the particles never completely stop and the particles maintains this kinetic energy unless its speed changes I.E. heating or cooling. when you add heat the particles move faster and when you cool they move slower.
It means when their are movement between the particles like vibration in a solid.

An attraction between particles of the SAME substance is called cohesion.
Links between particles in a substance...hmm....this is a tricky one, but if I'm right, it should be ATOMS. Does that fit?

Temperature is the average kinetic energy of a substance, As a substance gains kinetic energy, its particles begin to move faster. While solids vibrate in place, the particles in a liquid slip and slide past each other, and in gasses, the particles move even faster and further apart. As the kinetic energy of a substance increases, the particles collide with one another with greater force and frequency. Every time particles collide, there is friction between them. Just as your hands get warm when you rub them together, the particles begin to warm as they collide. This is why there is a direct relationship between the temperature and the kinetic energy of a substance.

Directly Proportionate Relationship
The dispersion relationship depends on the medium through which the waves propagate and on the type of waves (for instance electromagnetic, sound or water waves). For sound waves, the denser a medium is, the faster the waves will travel as particles will be closer together and thus energy can be transferred among them at a greater rate.
