Properties of Water Vocabulary

An object's mass divided by its volume is called ___________

• Weight
• Gravity
• Density
• Force

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

• Adhension
• Cohesion
• Surface Tension
• Specific Heat

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

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.

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.

Water is often called the "universal solvent" because many substances can be dissolved in water. What property of water allows it to be such a versatile solvent? 

• purity
• polarity and cohesion
• high heat capacity
• expansion upon freezing

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

Water is a universal solvent because it...

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

What does "like dissolves like" mean?

• polar solvents dissolve in polar solutes

• polar solutes dissolve in polar solvents

• non-polar solvents dissolve in polar solutes

• non-polar solutes dissolve in polar solvents
