of heat energy! I was a gas! No definite volume or shape! It was so fun to be free‚ I didn’t feel so bad for CO2 anymore! That day‚ I was one in billions because I underwent evaporation‚ and later on‚ I was one in billions because I underwent condensation! I knew i was condensing. I was getting closer and closer to all my other molecules. By chance‚ I then condensate into my own little well‚ where my molecule buddies ask me about my trip. When they asked me if

Cohesion differs from adhesion in being the force of attraction between adjacent particles within the same body; adhesion is the interaction between the surfaces of different bodies. The force of cohesion in gases can be observed in the liquefaction (condensation) of a gas‚ which is the result of a number of molecules being pressed together to produce forces of attraction high enough to give a liquid structure. Cohesion in liquids is reflected in the surface tension caused by the unbalanced inward pull

eye of the hurricane is usually very calm. Hurricanes form when winds hit very warm waters that reach at least 79 degrees Fahrenheit. Air starts to circulate which helps add more air and force‚ Another thing that helps the hurricane build up is condensation. Hurricanes are a large spinning mass of rotating winds‚ the winds reach more than 75 miles per hour. The tropical storms are usually in ocean areas called basins. These basins include the Atlantic Ocean‚ Gulf of Mexico‚ and the Caribbean Sea.

energy of sun light for water distillation. Solar energy is inexhaustible‚ available in abundance and pollution free. These features make it the best alternative among all renewable energy sources. A typical solar still works on the evaporation and condensation phenomena. Solar energy is utilized to first heat up the liquid water to evaporate it and produce vapour‚ then the vapour is allowed to get condense on a tilted glass cover. The condensate is then collected as the potable

FINGER TRACKING IN REAL-TIME HUMAN COMPUTER INTERACTION Nabeel Fasal/PET Engineering College ABSTRACT: For a long time research on human-computer interaction (HCI) has been restricted to techniques based on the use of monitor‚ keyboard and mouse. Recently this paradigm has changed. Techniques such as vision‚ sound‚ speech recognition‚ projective displays and location aware devices allow for a much richer‚ multi-modal interaction between man and machine. Finger-tracking is usage of bare
