The Properties Of Water!

What type of bond is formed between water molecules due to the opposite charges of hydrogen and oxygen?

• Ionic bond

• Covalent bond

• Hydrogen bond

• Metallic bond

Why does water have a high surface tension compared to most other liquids?

• Because of its low molecular weight

• Due to the hydrogen bonds between water molecules

• Because of its high viscosity

• Due to the covalent bonds within the water molecule

Which property of water allows it to move up through the roots of plants and into the stems and leaves?

• Adhesion

• Cohesion

• Capillary action

• Both A and B

What is unique about the density of water when it freezes?

• It increases

• It decreases

• It remains the same

• It becomes variable

Why does ice float on water?

• Because ice is cooler than water

• Because the density of ice is lower than that of liquid water

• Because ice has a higher molecular weight

• Because of the surface tension of water

What does the high specific heat of water mean for its ability to store heat?

• Water can store a small amount of heat before it gets hot

• Water cannot store heat

• Water can store a large amount of heat before it gets hot

• Water instantly releases any heat it absorbs

How does the high specific heat of water benefit the Earth's climate?

• It causes rapid temperature changes

• It prevents any form of life from existing

• It moderates temperature fluctuations

• It leads to extreme weather conditions

Why is water called the "universal solvent"?

• Because it can dissolve more substances than any other liquid

• Because it can dissolve gases only

• Because it is a pure substance

• Because it can dissolve solids only

Which property of water is responsible for its ability to dissolve so many substances?

• Its high specific heat

• Its molecular polarity

• Its surface tension

• Its density

What role does cohesion play in the behavior of water molecules?

• It causes water molecules to repel each other

• It leads to the formation of hydrogen bonds with other substances

• It causes water molecules to attract each other

• It decreases the boiling point of water
