Explain how the absorption of energy (heating) affects the speed of the particles in a substance

when a substance is cool the particles in the substance contracts, but when heated the particles expand and pressure becomes high that way the particles tend to move faster in the container, in other to escape.

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.
