Water Properties Chemistry

Electrons are shared unequally in a water molecule. This causes water to be ___________.

• Negatively charged

• Positively charged

• Polar

• Ionic

Water molecules stick together because of hydrogen bonding. This process is called _________________.

• Polarity

• Solvent

• Cohesion

• Adhesion

Because of its polarity, water is an excellent ________________.

• Solvent

• Solution

• Salinity

• Solute

Why does ice float in liquid water?

• The ice expands when it freezes, making it more dense than water.

• The ice expands when it freezes, making it less dense than water.

• The ice constricts when it freezes, making it more dense than water.

• The ice constricts when it freezes, making it less dense than water.

When water freezes in the ocean, the ice floats to the surface. What property explains this phenomenon?

• water expands when it freezes, making ice less dense than water

• water compacts when it freezes, making ice more dense than water

• hydrogen bonds in water push the ice to the surface

• ice is afraid of water, and avoids it

If this is a floating ice sheet, which property of water is this polar bear relying on? 

• Surface Tension

• Cohesion

• Adhesion

• Density

Water molecules stick to other substances because of the slight charge on other molecules. This process is called _________________.

• Polarity

• Salinity

• Cohesion

• Adhesion

What is the name of the type of bond that connects the hydrogen and oxygen in a water molecule? This is within the SAME water molecule. Strong bond.

• polar covalent bond

• nonpolar covalent bond

• hydrophobic interaction

What two elements make up water?

• Helium and oxygen

• Hydrogen and oxygen

• helium and carbon

• oxygen and carbon

The physical property of water, resulting from hydrogen bonding, that allows water molecules to stick to each other is referred to as:

• Cohesion

• Adhesion

• Homeostasis

• Capillary Action
