Properties of Water

What is the cause of surface tension?

• Because oxygen pulls on electrons more than hydrogen, making it partially negatively charged and the hydrogens partially positively charged.

• When water molecules are attracted to each other.

• When water molecules are attracted to molecules of a different kind.

• Because the cohesion property of water created surface tension on the water.

What is hydrogen bonding?

• Because the energy absorbed is used to break the hydrogen bonds before the temperature of the water begins to increase.

• When the partially negatively charged oxygen atom of the water molecule is attracted to a partially positively charged hydrogen atom on a neighboring water molecule.

• Because water molecules spread out when it freezes and is less than liquid water.

• When water molecules are attracted to each other.

Why is water polar?

• Because oxygen pulls on electrons more than hydrogen, making it partially negatively charged and the hydrogens partially positively charged.

• When water molecules are attracted to molecules of a different kind.

• Because the polar molecule is attracted to other polar molecules which include most compounds.

• When the partially negatively charged oxygen atom of the water molecule is attracted to a partially positively charged hydrogen atom on a neighboring water molecule.

What is adhesion in water?

• Because the cohesion property of water created surface tension on the water.

• Because the polar molecule is attracted to other polar molecules which include most compounds.

• When water molecules are attracted to molecules of a different kind.

• Because water molecules spread out when it freezes and is less than liquid water.

Why does water have a high heat capacity?

• Because the cohesion property of water created surface tension on the water.

• Because the polar molecule is attracted to other polar molecules which include most compounds.

• Because the energy absorbed is used to break the hydrogen bonds before the temperature of the water begins to increase.

• Because water molecules spread out when it freezes and is less than liquid water.

What is cohesion in water?

• When water molecules are attracted to molecules of a different kind.

• When water molecules are attracted to each other.

• Because the polar molecule is attracted to other polar molecules which include most compounds.

• Because the energy absorbed is used to break the hydrogen bonds before the temperature of the water begins to increase.

Why is water considered the universal solvent?

• When water molecules are attracted to molecules of a different kind.

• When water molecules are attracted to each other.

• Because oxygen pulls on electrons more than hydrogen, making it partially negatively charged and the hydrogens partially positively charged.

• Because the polar molecule is attracted to other polar molecules which include most compounds.
