Which of the following causes a solute to dissolve in a solvent?
A) Random movement of molecules of both the solute particles and the solvent molecules causes collisions which leads to dissolution.
B) The solvent decreases the surface area of the solute particles which leads to dissolution.
C) Non-random movement of the solute particles causes bonding between the solute particles and the solvent molecules.
D) The solute particles increase the surface area of the solvent which leads to dissolution.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
