Th solid particles are tightly packed together and has little space between them. The gases particles are far away from each other. The liquid particles are less closely packed together than solid but less than gases. Gases has highest space between them and can move easily, then liquid and least speed is of solid particles.
Thus, the answer is gas, solid and liquid.
