Which of the following is the CORRECT list of water's properties?
Read Carefully!
adhesion, cohesion, high specific heat, universal solvent
adhesion, cohesion, low specific heat, universal solvent
adhesion, no cohesion, low specific heat, universal solute
no adhesion, cohesion, high specific heat, universal solute
You body sweats to help prevent you from overheating. How does water regulate temperature?
it lets heat pass through it
it absorbs a lot of heat, then decreases in temperature
it absorbs a lot of heat, but only increases a little in temperature
heat is afraid of water and avoids it
Water is polar. What does that mean?
it is a molecule with opposite charges on opposite ends
it is a molecule with no charge
it is a molecule with identical charges on opposite ends
it is a molecule with too many protons
Water sticks well to many materials. What term relates to this property of water?
cohesion
adhesion
density
surface tension
What is the term for water's ability to defy gravity and climb up a tube?
Capillary Action
Specific Heat
Universal Solvent
Magic
Why does ice float?
water expands when it freezes, making ice less dense than water
water compacts when it freezes, making ice more dense than water
hydrogen bonds in water push the ice to the surface
ice is afraid of water, and avoids it
At what temperature does water Freeze?
0o C
100o C
32o C
-273o C
What are the bonds called between a slightly positive hydrogen in a polar molecule and a negatively charged atom?
Hydrogen Bonds
Water Bonds
Covalent Bonds
Bail Bonds
Which of the following is the correct molecular structure for water, H2O?
A water strider can skate along the top of a pond because:
covalent bonds result in water cohesion (surface tension)
hydrogen bonds result in water cohesion (surface tension)
water striders have adapted to take advantage of water cohesion
water striders are afraid of water and avoid it
Peyton wants to see if the salinity of water affects the population numbers of anchovies in a local body of water.
What would be the INDEPENDENT variable in his experiment?
Biomass of aquatic plants
Level of salinity in a given area
Water temperature
Total number of fish observed
