Question: Name and explain three properties of water that make it essential for sustaining life. Answer: The three properties of water that make it essential for sustaining life are: 1. Polarity and hydrogen bonding: Due to its polarity, water forms hydrogen bonds, making it resistant to temperature changes. This property helps in maintaining a stable environment for living organisms. 2. Cohesion and adhesion: Cohesion allows water molecules to stick together and facilitates nutrient transport in plants. Adhesion enables water to stick to surfaces, allowing capillary action and the transport of nutrients and waste throughout an organism's body. 3. Universal solvent: Water can dissolve a wide range of substances, which is vital for life as it allows various chemical reactions to occur within living organisms, facilitating the transport of nutrients and waste and enabling essential biochemical reactions.
