Water's Properties
Текст на Статията
- Water's Unique Properties
- Universal Solvent
- Cohesion and Adheasion
- Water is a unique substance because it can exist in three different phases(solid, liquid, and gas). Also, water is unique because it contains a number of different properties.
- High Surface Tension
- Water is a universal solvent because it can dissolve many substances. This is shown in the picture when it dissolves sand and other substances.
- High Heat Capacity
- Cohesion and Adhesion are shown in the picture when the water is sticking to the grass and the trees in the forest. This is because cohesion and adhesion deal with how water molecules stick with other molecules.
- Changes in density
- High surface tension is shown in the photo when the crab is able to walk on top of the water. This is because high surface tension deals with how tight together water molecules are at the surface of the water.
- High heat capacity deals with the amount of temperature that something can hold, without changing its chemical state of it. This is shown in the photo by the water being heated up by the fire, but it is still considered as water, based on its chemical state.
- Changes in density deals with the temperature of the water. When freezes, it has a different density than when it is at its liquid state. This is shown in the picture when the crab is standing on the ice. The crab is able to stand on the ice because it is more solid and has a different density than liquid water.
