Vocabulary
Polarity
What is an uneven distribution of charges? (Positive and negative side / magnets, ability to attach to things, etc.)
This makes water a bent molecule
This is why motor oil doesn't dissolve in water
What is non-polar?
This is why ice floats in water
What is ice is less dense?
Name for forces between molecules
What are Intermolecular forces (IMFs)?
Solubility
What is the ability to dissolve?
As temperature increases, this happens to gas solubility
What is decreases?
This principle is why things do or don't dissolve in water
What is the Like Dissolves Like Principle?
This is why things more dense than water can float
What is surface tension due to hydrogen bonding?
A compound that decreases surface tension
What is a surfactant?
Cohesion
What is water's ability to stick to itself?
As temperature increases, this happens to solid solubility
What is increases?
Dissolving is this kind of change
What is a physical change?
Water hits it's peak density at this temperature
What is 4 degrees celsius?
The reason for surface tension and cohesion
What are hydrogen bonds?
Adhesion
What is water's ability to stick to other things?
This creates polarity in water
Why is water being bent important?
What are hydration shells?
This causes ice to be less dense than water
What is anomalous expansion or hydrogen bond expansion?
This is how water moves throughout a tree
What is capillary action or cohesion/adhesion?
Solvent
What is the substance that is doing the dissolving?
This is how we measure molecular motion
What is temperature?
This difference is how we find out the type of bond
What is the electronegativity difference?
The reason lakes don't freeze all the way through during winter
What is insulation from the ice sheet?
Hypoxia
What is not enough oxygen?
