How are they different?
cohesion- the linking together of like molecules usually by hydrogen bonds.
adhesion- The linking together of different substances.

Why do they happen?
cohesion- because of Van Der Wall forces and hydrogen bonds
adhesion- electrostatic attraction 

Examples of each
cohesion- when water molecules evaporate the hydrogen bonds stick together to pull each other out. 
adhesion- water to plant cell walls]]> 2020-08-26 01:00:49 UTC https://padlet.com/pv220/yu7f6846c162kfzp/wish/698948714 pv220 https://padlet.com/pv220/yu7f6846c162kfzp/wish/698951240 Why does this happen?
Water molecules lose energy and does not vibrate or move around. Its molecule loses energy and gets stuck in a lattice structure in which they are farther apart from each other than in their liquid state. Ice is less dense than water.

How does this property affect aquatic organisms?
If water was less dense than ice, then all the bodies of water would eventually freeze over (if ice did sink), essentially making life on Earth impossible. ]]> 2020-08-26 01:02:45 UTC https://padlet.com/pv220/yu7f6846c162kfzp/wish/698951240 pv220 https://padlet.com/pv220/yu7f6846c162kfzp/wish/698952463 High specific heat- amount of heat required to absorb or lose 1 gram of a substance by one degree celsius (1 cal per gram per degree Celsius)

Calorie-the amount of heat required to raise or cool the temperature of 1g of water by 1 degree celsius

Heat of vaporization- the heat a liquid must absorb for 1 g to be converted to gas.]]> 2020-08-26 01:03:40 UTC https://padlet.com/pv220/yu7f6846c162kfzp/wish/698952463 pv220 https://padlet.com/pv220/yu7f6846c162kfzp/wish/698953460 Why is it versatile? Water is a polar molecule which allows it to dissolve more substances that any other liquid.


Hydrophilic vs Hydrophobic substances
-Hydrophilic: Has an affinity for water
-Hydrophobic: Does not have an affinity for water]]> 2020-08-26 01:04:29 UTC https://padlet.com/pv220/yu7f6846c162kfzp/wish/698953460 pv220 https://padlet.com/pv220/yu7f6846c162kfzp/wish/698956282 2020-08-26 01:06:46 UTC https://padlet.com/pv220/yu7f6846c162kfzp/wish/698956282 pv220 https://padlet.com/pv220/yu7f6846c162kfzp/wish/698956883 What is it?
H+ concentration in a particular substance. It is a logarithmic function

Scale
Determines if a substance is an acid (1-7) or a base (7-14).]]> 2020-08-26 01:07:19 UTC https://padlet.com/pv220/yu7f6846c162kfzp/wish/698956883 pv220 https://padlet.com/pv220/yu7f6846c162kfzp/wish/698957452 What are they?
Acid- Substance that increases the H+ concentration in a solution.

Base- Substance that reduces H+ concentration in a solution.

Most present type of ion:
Acid- H+
Base- OH-

pH
Acid- 1-7
Base- 7-14]]> 2020-08-26 01:07:46 UTC https://padlet.com/pv220/yu7f6846c162kfzp/wish/698957452
