is the particle model of matter theory that if matter/particles are heated then the particles expand and move faster and if the matter/particles are cooled then the particles contract and move slower?

All of physics considers matter to be composed of subatomic particles. There's not a competing theory. Superstring/M-brane theory just tries to get down to smaller detail.
As the second reference explains, thermal expansion is caused by the increased motion of particles. The particles themselves don't expand.

All matter is composed of three particles, protons, neutrons and electrons, the electron is indivisible, the proton is made of subatomic particles called quarks and the neutron is a proton with an electron embedded in it. All of these particles were created in the big bang.

That is thermodynamics. A particle model would be the Standard Model, which studies the particles and their sub particles themselves and their conservation laws.
