Properties of Water

What is currently recognized as the most common solvent?

• water

• salt

• hydrogen

• sugar

This table lists the density of four different substances.

If water has a density of 1.0 g/cm ³ , which substance will float on the surface of water?

• Substance W, because it is less dense than water

• Substance X, because it is more dense than water

• Substance Y, because it is more dense than water

• Substance Z, because it is less dense than water

What is the density of water?

• 0 g/ml

• 1 g/ml

• 10 g/ml

• 100 g/ml

Which density will float on water?

• 0.7 g/cm³

• 1.2 g/cm³

• 3.5 g/cm³

• 11.4 g/cm³

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

What is the density according to the graph?

• 50 g/mL

• 1 g/mL

• 25 g/mL

• 100 g/mL

Which of the following statements is true about density?

• If an object is is less dense than water it will sink in water.

• If an object is more dense than water it will sink when put into water.

The objects density must be less than (a)   in order to float in water.
