You can balance a seesaw when the torques are balanced in equilibrium â that is, when the sum of the torques is zero and the torques on one side of the fulcrum are equal and opposite to the torques on the other side. For this activity the force is just the weight of the mass given by w = mg.
Likewise, as elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation.he boiling point is the temperature at which the vapor pressure is equal to the atmospheric pressure around the water. Because of this, the boiling point of water is lower at lower pressure and higher at higher pressure.
A constant pressure (or isobaric) surface is a surface in the atmosphere where the pressure is equal everywhere along that surface. For example, the 100 millibar (mb) surface is the surface in the atmosphere where the pressure at every point along that surface is 100 mb.Since pressure decreases with height, the altitude of the 100 mb surface is higher than the 500 mb surface, which is likewise higher than 1000 mb.or example, the 100 millibar (mb) surface is the surface in the atmosphere where the pressure at every point along that surface is 100 mb. Since pressure decreases with height, the altitude of the 100 mb surface is higher than the 500 mb surface, which is likewise higher than 1000 mb.
