What are the 4 main properties of water?
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
- Polarity. A water molecule is slightly charged on both ends.
- Cohesion. Hydrogen bonds hold water molecules together, as seen in the picture above.
- Adhesion.
- High Specific Heat.
What is the impact of water scarcity?
Among the economic implications of water scarcity is the impact on businesses worldwide leading to higher operating costs and staying competitive. For global firms controlling costs is difficult but it worsens when the price of water increases exponentially to where margins shrink precariously.
