Understanding how the particles of matter behave is vital if we hope to understand science! The model also helps us to understand what happens to the particles when matter changes from one state to another. For an intuitive understanding of models in state-space form, addition and subtraction of terms in state equations can be interpreted as elements that contribute to a change in the system states.
