Question

a teacher uses a computer simulation to show how gas particles move at the atom level. what type of model is this? a computer model a physical model a mental model or analogy

Explanation:

A computer model uses computer simulations to represent systems (like gas particle movement at atomic level). A physical model is a tangible, physical representation (not applicable here as it's a simulation). A mental model is conceptual, not a simulation. So the correct option is the one related to computer simulation.

Answer:

A. A computer model
