Multiple Choice

freezing lake water

• liquid to solid

Multiple Choice

Why does frozen water float?

• constant movement of the water keeps the ice afloat

• surface tension prevents the ice from sinking

• frozen water has a lower density than liquid water

• air currents keep the ice on the surface

Multiple Choice

Water in a cup will help prevent the cup from burning up over a flame due to this property of water

• high specific heat

• capillary action

• surface tension

• greatest density at 4 ^oC

Multiple Choice

Capillary action is....

• adhesion

• cohesion

• change in matter (heat of fusion)

• both adhesion and cohesion

Multiple Choice

What is the only substance with a neutral pH of 7?

• Milk
• Orange Juice
• Water
• Blood

Multiple Choice

A(n) _______ is a substance with a pH greater than 7.

• Base
• Acid
• Buffer
• Water

Multiple Choice

A(n) ______ is a substance with a pH less than 7

• Acid
• Alkaline
• Base
• Buffer

Multiple Choice

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes
• Capillary action pulls the water molecules like a chain
• Water is pulled by gravity
• Water’s cohesion causes it to “pull” towards the leaves

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

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

Which of the following is LEAST likely to dissolve in water?

• nonpolar fats and oils
• polar sugar molecules
• salt made of a positive sodium ion and a negative chloride ion

Multiple Choice

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

• the oxygen end

• neither end is positive

Multiple Choice

Attractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds

Multiple Choice

What word describes when water is attracted to other substances?
