UNIT 1.1 QUIZ

What is the polarity of water?

• Polar

• Non-Polar

What is the correct description of a water molecule?

• 2 Oxygen Atoms With A Polar Covalent Bond To 1 Hydrogen Atom

• 1 Oxygen Atom With A Hydrogen Bond To 2 Hydrogen Atoms

• 1 Oxygen Atom With A Polar Covalent Bond To 2 Hydrogen Atom

• 1 Oxygen Atom With A Non-Polar Covalent Bond To 2 Hydrogen Atoms

A ________ Bond Is A Bond Between An Oxygen Atom & A Hydrogen Atom From 2 Different Water Molecules

Hydrophilic​

• Water Hating

• Hydrogen Loving

• Water Loving

• Hydrogen Hating

Polar Molecule

• Negative Charge

• Positive Charge

• Positive & Negative Charge

• Neutral

What Causes Capillary Action?

• Water Is Heated Up Causing Kinetic Energy To Disperse Water Molecules Into The Air

• Water Molecules Have No Surrounding Polar Charges To Attract To, Therefore Water Molecules Pack Tightly Together

• The Adhesive Property Of Water Allows It To Attract Towards Polar Molecules And Travel Against Gravity

• Water’s Cohesive Property In A Situation Where Water Is In Contact With A Hydrophilic Surface

What Factor Decides The State Of Water

• Temperature

• Pressure

• Polarity

• Density

When Heat Within Water Is Raised Significantly, What Happens To The Water?

• Kinetic Energy Rises Within The Molecules And Causes The Complete Breakaway Of Hydrogen Bonds

• Kinetic Energy Lowers Within The Molecules And Causes Molecules To Break Hydrogen Bonds

• Kinetic Energy Rises Within Molecules And Causes The Molecules To Form Hydrogen Bonds

• Kinetic Energy Lowers Within Molecules And Causes The Molecules To Disperse Into The Air As Hydrogen Bonds Break

What Happens To Organisms When Frozen?

Which Of The Following Is True When Water Evaporates?

• Water Molecules Form Hydrogen Bonds Due To High Kinetic Energy

• The Surface Below The Evaporated Liquid Cools As Heat Leaves Through Kinetic Energy In Evaporated Molecules

• Hydrogen Bonds Begin To Break, Causing The Molecules Within The Body To Raise Body Temperature

• Kinetic Energy Is Stored In The Body As Water Is Evaporated.
