<em>It is used to gain improved </em><em>understanding of the processes and systems. </em>
Explanation:
However, every model have some limitations because they are not the representative of every possible scenario. For instance, relationship between time and distance is the idea model, study of cell and its various parts uses physical model, predicting earthquake uses computer model.
