Which of the following is not true about a model?
It cannot represent a process
A model can indeed be mental, such as an idea or mental picture, or physical, such as a tangible replica, so this statement is true.
A model is created to give a conceptual representation of a phenomenon or concept, making an abstract idea easier to visualise, so this statement is true.
A model explains a set of observations, inferences, ideas or events by representing them in a simplified form, so this statement is true.
A model can represent not just an object but also a process — for example, a diagram of the water cycle or of digestion is a model of an ongoing process — so the claim that a model cannot represent a process is false.
Hence, the statement that is not true about a model is that it cannot represent a process.

French scientist Henri Becquerel was working on phosphorescent materials, which glow in the
dark after exposure to light. He believed that sunlight was the reason that the crystal would burn
its image on a photographic plate. On a stormy day in $1896$, he decided to leave it for few days
and resume his experiments later. A few days later, he took his crystal out of a darkened drawer.
He noticed that the image burned on the plate was 'fogged' which meant that the crystal had still
emitted rays, despite the lack of sunlight.
