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.
Approximately 75% of the Earth's surface is covered by saltwater oceans. About 71 percent of the Earth's surface is water-covered, and the   oceans hold about 96.5 percent â¦of all Earth's water. But water  also exists in the air as  water vapor, in  rivers and  lakes, in icecaps and  glaciers, in the ground as soil moisture and in  aquifers, and even in you and your dog.
