The BOD POD is based on the same whole-body measurement principle as hydrostatic or underwater weighing - the previous gold standard of body composition testing, which requires complete submersion in a water tank. BOD POD Body Composition System to Descend On San Francisco's IHRSA Convention.
Clouds are made of tiny drops of water or ice crystals that settle on dust particles in the atmosphere. The droplets are so small-a diameter of about a hundredth of a millimetre-that each cubic metre of air will contain 100 million droplets.louds are usually produced through condensation-as the air rises, it will cool and reducing the temperature of the air decreases its ability to hold water vapour so that condensation occurs. The height at which dew point is reached and clouds form is called the condensation level.
Fog is a cloud that is in contact with the ground. Much like clouds in the sky, it forms when the air becomes supersaturated, meaning that it can no longer hold moisture in the form of vapor. As a result, water precipitates out of the air, forming a fine mist of water droplets.
