2.2 Properties of water copy

Multiple Choice

Which end of the water molecule has a slightly positive charge?

• the oxygen end
• the hydrogen end
• both ends are slightly positive
• neither end is positive

Multiple Choice

The term that describes the idea the hydrogen atoms of a water molecule has the positive charges and oxygen atom has a negative charge. These charges are opposite which is why the water molecule is able to stay bonded.

• Polarity
• Surface Tension
• Specific Heat
• Heat of Vaporization

Multiple Choice

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

Multiple Choice

When a molecule has an opposite electrical charge on each end, it is known as what?

• cohesion
• polar molecule
• hydrogen bond
• solution

Multiple Choice

True or False: Hydrogen bonds are very weak, which allows for many of the chemical characteristics found in water.

• True

• False

Multiple Choice

Water has a high specific heat capacity. This means that

• it takes a lot of energy to change the temperature of water

• water changes temperature very quickly and easily

• water temperature doesn't change at all

Multiple Choice

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.
•  Water acts as a buffer.

Multiple Choice

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.
• Ice is warmer than liquid water.

Multiple Choice

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

Multiple Choice

What is cohesion?

• Water's ability to stick to itself
• Water's ability to stick to other substances
• The strength of the cohesion of all the water molecules combined
• Tape, glue and other adhesives

Multiple Choice

When water molecules stick easily to other water molecules, this is called what?

• cohesion
• adhesion
• solution
• polar molecule

Multiple Choice

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

Multiple Choice

A combination of cohesion & adhesion that allows water to climb tubes

• capillary action

• surface tension

Multiple Choice

Water is a universal solvent because it...

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

Multiple Choice

The ability of water molecules to stick to each other, creating surface tension is called:

• Cohesion

• Adhesion

• Insulation

• Ph

Multiple Choice

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

• adhesion
• capillary action
• surface tension
• polarity

Multiple Choice

What is cohesion?

• The ability of a molecule to "stick" to itself

• The ability of a molecule to "stick" to other molecules

• Large amounts of energy are required to change the temperature of a substance

• A well-organized and efficient team

Multiple Choice

What characteristic is shown in the image?

• Polarity

• Hydrogen Bonds

• Cohesion

• Adhesion

Multiple Choice

What property of water allows for water to act as a temperature regulator for the world?

• Cohesive Behavior

• Expansion Upon Freezing

• High Specific Heat

• Universal Solvent

Multiple Choice

Why does ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Multiple Choice

The fact that water can stick to other substances is called:

• Ph

• Adhesion

• Cohesion

• Insulation

Multiple Choice

The "skin" that forms on water due to cohesion is called

• surface tension

• capillarity

• adhesion

Multiple Choice

The property that allows water (and other substances) to stick to other objects is:

• Adhension
• Cohesion
• Surface Tension
• Specific Heat

Multiple Choice

Water is a universal solvent because it...

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