Properties of Water - Review Day

Describe COHESION.

• Water molecules attracted to other substances.

• Water molecules climbing upwards against the force of gravity.

• Water molecules dissolving many substances because of its polarity.

• Water molecules attracted to other water molecules.

Attractions between water molecules are called

• Covalent bonds

• Ionic bonds

• Polar bonds

• Hydrogen bonds

Why does ice float?

• As water freezes, the molecules move farther apart and its density decreases.

• As water freezes, it takes up more hydrogen from the atmosphere

• As water freezes, air becomes trapped between the water molecules.

• As water freezes, it takes up more oxygen from the atmosphere

Which temperature is the boiling point of water?

• 0 degrees Celsius
• 32 degrees Celsius
• 100 degrees Celsius
• 212 degrees Celsius

Large bodies of water do not quickly fluctuate in temperature. Why?

• Water is a solvent.
• Water has a high heat capacity.
• Water acts as a buffer.
• Water is non-polar.
