Properties Of Water: Unique properties of water

The video tutorial explains the unique properties of water, starting with its molecular structure and polarity, which lead to hydrogen bonding. It covers cohesion and adhesion, highlighting how these properties affect water's behavior. The tutorial discusses the crystalline structure of ice and water's thermal properties, including its high specific heat index. It also addresses how air pressure influences water's boiling point and the impact of dissolved minerals, distinguishing between hard and soft water. Finally, it explores water's role as a universal solvent, detailing hydrophilic and hydrophobic substances and their applications.

What causes water molecules to be attracted to each other?

• Electrostatic forces

• Gravitational pull

• Hydrogen bonds

• Magnetic forces

Why does ice float on water?

• Ice has a higher temperature

• Ice has a crystalline structure that is less dense

• Ice is denser than water

• Ice is lighter due to air bubbles

How does air pressure affect the boiling point of water?

• Higher pressure lowers the boiling point

• Lower pressure raises the boiling point

• Boiling point changes with barometric pressure

• It remains constant regardless of pressure

What is the main difference between hard and soft water?

• Soft water is more viscous

• Soft water has a higher pH level

• Hard water contains minerals like calcium and magnesium

• Hard water contains more dissolved gases

What term describes substances that dissolve well in water?

• Hydrophobic

• Hydrophilic

• Nonpolar

• Amphipathic
