The form of energy associated with the position or arrangement of objects in a system. Second Law of Thermodynamics. States that no enrgy transformation is perfectly effiecients; in a closed system, some energy from every transformation will always be lost as heat, with a corresponding increase in entropy.
When we think of water, we think of rain, lakes and rivers. because they are parts of our daily lives. Water is also found in the atmosphere, underground, in. snow, ice, seas and oceans. It is in constant motion and recycles itself through the Water Cycle. Most of the earthâs water is salty or permanently frozen. 95.1% of water on earth is estimated. to be salt water. Fresh water total only 4.9% of all water on earth. Fresh water is found in. ice, lakes, rivers, streams and underground.
In his textbook ''Introduction to Oceanography,'' Dr. Ross estimated that the ocean had 97.2 percent of the earth's total water and put the freshwater ice caps and glaciers at 2.15 percent. Saline lakes and inland seas would add a trace of salt water, or 0.008 percent of the global total. Relatively small amounts of fresh water are also found in groundwater (0.625 percent of total water), freshwater lakes (0.009 percent), the atmosphere (0.001 percent) and rivers and streams (0.0001 percent.)
