Atoms+molecules moving around.
Atomic theory. And in much more weird detail: quantum physics.
kinetic theory.
The kinetic theory of matter states that matter is made of particles whose speed is dependent on their mass and temperature. The kinetic theory states that particles in matter are always in motion.
kinetic theory of gas is defined with the help of maxwell distribution
Kinetic theory and Heat transfer are both in motion, in Kinetic theory all states of matter are in vigorous motion and Heat transfer is associated with the motion of atoms or molecules.

Neils Bohr came up with the kinetic Theory of Matter, also known as: The Molecuar Theory of Matter, and The Bohr Model.
