Water's Structure
The shape of a water molecule
What is bent (or V-shaped)?
Water molecules sticking to other water molecules
What is cohesion?
The reason ice floats on liquid water
What is ice is less dense than liquid water?
Whether water has a high or low specific heat capacity
What is high?
Water's nickname due to its ability to dissolve many substances
What is the universal solvent?
The reason oxygen attracts electrons more strongly than hydrogen in a water molecule
What is oxygen has more protons in its nucleus?
Water molecules sticking to other materials like glass
What is adhesion?
The temperature at which water reaches maximum density
What is 4°C?
The property that describes how much energy is needed to raise 1 kg of water by 1°C
What is specific heat capacity?
The property of water that allows it to dissolve ionic and polar substances
What is polarity?
The term for the partial charges (δ+ and δ-) on a water molecule
What is polarity?
The property that allows water striders to walk on water
What is surface tension?
The structure hydrogen bonds form in ice that makes it less dense
What is an open crystal lattice?
The reason a shallow pond heats up faster than a deep lake in summer
What is the deep lake has more water mass to heat / takes longer for heat to distribute?
What happens to water's density when salt dissolves in it
What is density increases?
The type of bond that forms BETWEEN water molecules
What is a hydrogen bond?
The movement of water up a paper towel, using both cohesion and adhesion
What is capillary action?
The location of the densest water (at 4°C) in a winter lake
What is the bottom of the lake?
How water's high heat capacity protects coastal aquatic organisms
What is it absorbs large amounts of heat with minimal temperature changes, keeping habitats stable?
The reason water mixes vertically during fall turnover in a lake
What is surface water cools and becomes denser, sinking toward the bottom?
The properties most affected if water's bent shape were straightened out
What is polarity and hydrogen bonding?
The two forces working together when water climbs through narrow spaces against gravity
What are cohesion and adhesion?
How floating ice helps organisms survive winter in cold lakes
What is ice insulates the liquid water below, keeping it around 4°C?
What happens to hydrogen bonds when water absorbs heat energy
What is they break?
What happens to a pollutant during fall turnover and why it matters to organisms
What is it gets distributed throughout the lake, exposing all organisms to it?
