Chemistry Water Properties

Water is a universal solvent because it...

• It can be found anywhere

• It freezes when it gets cold

• Dissolves most substances

The tightness across the surface of water that enables paper clips to float is ____________.

• adhesion

• capillary action

• surface tension

What is the chemical formula for water?

• H20

• H₂O

• H₂O₂

Refer to the picture; the meniscus is occurring because of:

• Adhesion

• Cohesion

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

Capillary Action is key for

• Water moving from roots to leaves in plants

• Air moving from mouth to lungs

• Ice floating on water

Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?

• Water is an acid.

• Water is a versatile solvent.

• Water has a high heat capacity.

Why does ice stay at the top of oceans instead of sinking to the bottom?

• Ice is colder than liquid water.

• Ice is less dense than liquid water.

• Ice is more dense than liquid water.

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

• Water is a solvent.

• Water has a high heat capacity.

• Water is non-polar.
