What are the properties of the energy levels in a system of 2 particles in a box?

In a system of 2 particles in a box, the energy levels are quantized, meaning they can only have specific values. The energy levels are determined by the size of the box and the mass of the particles. The particles can occupy different energy levels, with each level corresponding to a specific amount of energy. The energy levels are spaced apart evenly, and the particles cannot have energy levels in between these quantized values.
