Write a paragraph about these words: mass, volume, density, force, pressure, air pressure, weight, and altitude. |
The amount of mass in a given volume of air is its density. The force pushing on an area to a surface is pressure. Air pressure is the result of the weight of a column of air pushing on an area. As altitude increases, air pressure decreases. As air pressure decreases so does density. |
