Two flasks are connected with stopcock. The first flask has a volume of 5 liters and contains nitrogen gas at a pressure of .75 atm. The second flask has a volume of 8L and contains oxygen gas at pressure of 1.25 atm. When the stopcock between the flasks is opened and the gases are free to mix what will the pressure be in the resulting mixture?

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.
