Properties of Water Practice

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

• Water is a solvent.
• Water has a high heat capacity.
• Water acts as a buffer.
• Water is non-polar.

What two elements make up water?

• Helium and oxygen
• Hydrogen and oxygen
• helium and carbon
• oxygen and carbon

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

The fact that ice floats on liquid water is due to the fact that water's solid is ___________ than it's liquid form

• less polar
• more polar
• less dense
• more dense

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

• adhesion
• capillary action
• surface tension
• polarity

Which statement explains why water molecules stick together?

• both sides are negative
• one side has a positive charge and the other side has a negative charge
• one side has a negative charge adn the other side has a neutral charge
• both sides are positive

Water molecules are polar molecules. What is meant by the term polar molecule?

• a molecule that has no charge on one end and either an overall negative or positive charge on the other end

• a molecule that has an overall positive charge on one end, as well as an overall positive charge on the other end

• a molecule that has an overall negative charge on one end, as well as an overall negative charge on the other end

• a molecule that has an overall positive charge on one end and an overall negative charge on the other end
