1. what characteristic of water give rise to its unique properties?
2. list the properties of water that are necessary for life on earth?

waters polarity is responsible for most of its unique properties that are essential for life on earth. the unique properties of water include cohesion, adhesion, capillary action, surface tension, the ability to dissolve many substances, and high specific heat.

Explanation:

1. Water's polarity leads to hydrogen - bonding. This causes cohesion (water molecules sticking to each other), adhesion (water molecules sticking to other substances), capillary action (movement in narrow spaces), and high surface tension. Its high specific heat capacity helps regulate temperature. These are key characteristics giving rise to its unique properties.
2. Cohesion allows for surface tension which is important for water striders etc. Adhesion and capillary action help in water transport in plants. High specific heat stabilizes temperature for aquatic life. Its solvent ability is crucial for biochemical reactions. These properties are necessary for life on Earth.

Answer:

1. Polarity leading to hydrogen - bonding, causing cohesion, adhesion, capillary action, surface tension and high specific heat.
2. Cohesion, adhesion, capillary action, high specific heat, solvent ability.
