In your own words describe the difference between the movement of particles in liquids and the movement of particles in gases.

In liquids, particles are slightly spaced from each other and move around somewhat freely, but still bump into each other. Gases on the other hand move randomly and rarely bump into each other, thus they are more spaced out.

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
