A solution is a mixture that forms when one substance dissolves another.It can dissolve gases such as carbon dioxide and oxygen.As the negative side of water forms bonds with the Na+ and the positive side is attracted to Cl- ions in a crystal of salt (NaCl), it pulls these ions into solution, the crystal dissolves.The ability of water to dissolve many substances allows water to deliver essential nutrients to cells in plants, animals, and other organisms.This property of water allows lakes, streams, and ocean ecosystems to maintain stable temperatures, even if air temperatures change dramatically.Dissolving salt is an example.

A solution is a mixture that forms when one substance dissolves another. The substance that does the dissolving is called the solvent. Water is called the universal solvent because it can dissolve more substances than any other known substance. The main property of water that makes it such a good solvent is its polarity. The charged ends of the water molecule attract the molecules of other polar substances. (like dissolves like) It can dissolve substances like sugar, bleach, salt. It can dissolve gases such as carbon dioxide and oxygen. Dissolving salt is an example. As the negative side of water forms bonds with the Na+ and the positive side is attracted to Cl- ions in a crystal of salt (NaCl), it pulls these ions into solution, the crystal dissolves. The ability of water to dissolve many substances allows water to deliver essential nutrients to cells in plants, animals, and other organisms. Water dissolves nutrients in our food. It does not dissolve nonpolar substances like oil and wax. They don’t like water and are called hydrophobic. Specific heat is the amount of heat needed to increase the temperature of 1 kg of a substance by 1°C. Compared to other substances, water requires a lot of heat to increase its temperature. The unit of specific heat is joule per kilogram per degree Celsius (J/kg • 0G). The specific heat of water is very high-4,184 J/kg • °C. Therefore, water takes a long time to heat up or cool down. Water has a high specific heat because of the strong attraction among water molecules (cohesion). This property of water allows lakes, streams, and ocean ecosystems to maintain stable temperatures, even if air temperatures change dramatically. So that the air over water is cooler than the air over land on hot days. The high specific heat of water also helps your body to maintain a constant internal environment
