In heat, the atoms or molecules making up any substance (e.g. a rock) start to move faster, because they are gettting more energy from the heat. since they move faster, they are also able to vibrate (in the case of a solid) more, and so can get further away from the centre of the objext.
This causes the illusion of expansion, although the mass of the object remains the same.
