Cohesion & Adhesion
Water molecules sticking together is called?
What is Cohesion?
Why does ice float?
Why is it less dense than liquid water?
What makes water a polar molecule?
Unequal sharing of electrons (O is negative, H is positive)
What property allows bugs to walk on water?
What is surface tension?
Capillary action helps humans with...
digestion, blood flow, nutrient transfer
Water molecules sticking to other surfaces is called?
What is adhesion?
What prevents lakes from freezing solid?
Why does Ice insulate the water below?
What kinds of substances dissolve in water easily?
What are polar & ionic molecules?
Surface tension is caused by this property.
What is cohesion/ hydrogen bonding?
This property explains why coastal areas have mild climates.
What is high specific heat/ humidity?
Both cohesion & adhesion help plants with this process
What is capillary action?
Which property allows water to absorb heat without big temperature changes?
What is high specific heat?
Because water dissolves many substances it is called the _________ solvent.
What is universal?
Which property allows water to climb plant stems?
What is capillary action?
How does sweating cool the body?
Clings to your body via adhesion and cools you down
clings to itself via cohesion
This property explains why you can see a meniscus in a graduated cylinder.
What is Adhesion?
This property of water helps regulate Earth's climate.
What is high specific heat?
Why can't water dissolve fats/oils?
They are nonpolar.
Adhesion is water sticking to ____________.
What is other substances?
Humidity effects this weather factor
temperature/ heat index
Without cohesion, this process in tall trees would not occur.
What is transpiration/ water transport?
Why is floating ice important for aquatic life?
How does polarity let water dissolve in salt?
O- attracts Na+ and H+ attracts Cl-
Explain how capillary action helps keep tall trees alive.
Moves water from roots to leaves
This property allows nutrients to dissolve in our bloodstream.
