We can’t possibly follow every detail of the motions of all these particles, nor would we want to if we could. Consider a chunk of metal, containing perhaps 1023 ions and 1023 conduction electrons.
Anything big enough to see with our eyes (or even with a conventional microscope) has enough particles in it to qualify as a subject of thermal physics. Examples include the air in a balloon, the water in a lake, the electrons in a chunk of metal, and the photons (electromagnetic wave packets) given o⇧ by the sun.
Preface Thermal physics deals with collections of large numbers of particles-typically 1023 or so.
