Water

?
What are the most important characteristics of water?
Denisty, solvent, high latent heat, liquid, high specific heat capacity, cohesion and surface tension, reactant.
1 of 10
Why is water as a liquid important to life?
Provides a habitat for aquatic organisms, makes up major component of tissues in living organisms, reaction medium.
2 of 10
Why is high specific heat capacity important to life?
Provides a stable temperature to live in.
3 of 10
Why is water as a solvent important to life?
Most things dissolve in water, it is transport for vital nutrients.
4 of 10
Why is cohesion and surface tension important to life?
Cohesion allows water to be pulled up a stem to provide plants with water. Surface tension allows insects like pond skaters to walk on water.
5 of 10
Why is density important to life?
Provides habitat for aquatic organisms, ice is less dense than water, insulation in ponds in winter.
6 of 10
What is a polar molecule and how is it formed?
When negative electrons are not shared equally they create a sub charge making one atom in the bond slightly more negative and the other atom slighly more positive.
7 of 10
How do polar molecules interact with eachother?
Because of a molecules polar properties they are highly attracted to eachother giving them cohesion.
8 of 10
Why is high latent heat of vaporization important to life?
Water helps to cool living things and keep their temperature stable.
9 of 10
Why is water as a reactant important to life?
For digestion and sythesis of large biological molecules.
