As distance between two capacitor plates decreases, capacitance increases - given that the dielectric and area of the capacitor plates remain the same. So, why does this occur? As distance between two capacitor plates decreases, capacitance increases - given that the dielectric and area of the capacitor plates remain the same.
So, in summary, as the distance between two capacitor plates decreases, the capacitance increases because the electric field between the plates becomes stronger, resulting in more polarisation of the dielectric material and a greater charge imbalance on the plates.
Let's say a charged capacitor A is two metal plates 1 cm apart. And a non-charged capacitor B is two metal plates 0.1 cm apart. When we let the side of capacitor B touch the side of capacitor A, what happens?
To see how this happens, suppose a capacitor has a capacitance C 0 when there is no material between the plates. When a dielectric material is inserted to completely fill the space between the plates, the capacitance increases to is called the dielectric constant.
To find the capacitance C, we first need to know the electric field between the plates. A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates.
where A is the area of the plate . Notice that charges on plate a cannot exert a force on itself, as required by Newton’s third law. Thus, only the electric field due to plate b is considered. At equilibrium the two forces cancel and we have The charges on the plates of a parallel-plate capacitor are of opposite sign, and they attract each other.

Why/how does distance affect capacitance?
When we let the side of capacitor B touch the side of capacitor A, what happens? Well, opposite charges like to be close to each other, so the charges go from the capacitor A to the capacitor B. We say capacitor B has larger capacitance than capacitor A, when charges prefer to be go from A to B.Or maybe this is better:
