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 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.

The 'particle model of matter' is sometimes called the 'kinetic theory of matter' because it explains the properties of matter in terms of the motion and interaction of particles. This theory posits that all matter is composed of tiny particles that are in constant motion, and their kinetic energy determines the state of the matter—solid, liquid, or gas. The kinetic theory helps to explain phenomena such as temperature, pressure, and phase changes based on the movement and behavior of these particles.

Neils Bohr came up with the kinetic Theory of Matter, also known as: The Molecuar Theory of Matter, and The Bohr Model.
The kinetic theory of matter for radiation states that radiation consists of particles (photons) that move at the speed of light and transfer energy when they interact with matter. This theory helps explain how radiation behaves in terms of absorption, emission, and scattering processes.
The kinetic theory of matter states that matter is made up of tiny particles in constant motion. These particles have kinetic energy that increases with temperature, causing them to move faster.
