The motion of particles In different states is difficult to observe. A student used computer software to represent the movement of particles in the solid state. Which type of scientific model did the student use? A. a simulation because it imitates an intrinsic process in the molecule

B. a simulation because it helps visualize the orientation of atoms in the molecule

C. a 3-dimensional model because it helps visualize the orientation of atoms in the molecule

D. a 3-dimensional model because it imitates intrinsic processes in the molecule
