Exploring Water's Unique Properties

When water molecules stick easily to other water molecules, this is called what?

• cohesion

• adhesion

• solution

• polar molecule

Which property of water allows it to absorb a lot of heat without a significant increase in temperature?

• Low specific heat

• High specific heat

• Low heat capacity

• High thermal conductivity

What causes water to be a polar molecule?

• The equal sharing of electrons between hydrogen and oxygen

• The unequal sharing of electrons between hydrogen and oxygen

• The linear shape of the water molecule

• The presence of ionic bonds

Which of the following best explains why water is known as the "universal solvent"?

• It can dissolve all substances

• It can dissolve many substances due to its polarity

• It can dissolve only ionic compounds

• It can dissolve only non-polar substances

What is the primary reason for water's cohesive properties?

• Solubility

Why does ice float on water?

• Ice is denser than water

• Ice is less dense than water

• Ice has a higher specific heat than water

• Ice has a lower specific heat than water

Which of the following best describes adhesion in water?

• Water molecules sticking to each other

How does the polarity of water affect its solubility properties?

• It allows water to dissolve non-polar substances easily

• It allows water to dissolve polar and ionic substances easily

• It prevents water from dissolving any substances
