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.
Anyone who has ever tasted seawater knows that it is truly salty. The salty residue left on swimsuits after theyve been in the ocean is further evidence of the oceans salinity. Salinity is a measure of how much salt is dissolved in water.The average salinity of seawater for all Earths oceans is about 35 grams of dissolved salts per kilogram of seawater. This is shown as 35 parts per thousand, or 35.he salty residue left on swimsuits after theyve been in the ocean is further evidence of the oceans salinity.
