To see the enormous strength of steam, you do not have to search further than witnessing the eruption of geysers or the explosion of gasses that occurs when lava mix with oceans. Man has witnessed such sights and for long tried to control the crude power of steam using technology ranging from the tea kettle to the modern nuclear power plant. Regardless of the level of technology involved, steam power comes down to one basic principle: When water is heated to point of vaporization, the vaporized water occupies more space than the liquid water.This is because solids, liquids and gases are each binded together by different strength of inter molecular forces . In solids,the molecules are compacted together. In liquids, they have more spaces apart. And in gases,such as steam, they are further apart. If a can of soup is heated on fire, the contents will turn to vapour and later expand ,making the can explode to let out the pres...
