How can we observe the cohesion and adhesion of water? Give examples that an average person could understand. Also, you might use counter-examples, of substances that don't display cohesion or adhesion?
We can observe the adhesion and cohesion of water In many different ways. They are really everywhere in nature. You may see a bug actually on top of they water floating there. Yeah, that is the water being cohesive. The water molecules are sticking to each other in such a way that they hold the insect up. Another thing you might see is a larger insect. When it tries to land on the water it sinks and gets submerged because even though the water is cohesive, it does not have the strenth to hold a heavy object.
In class, how did we model water molecules? How could this model be used to explain cohesion and adhesion? Choose one of your water examples from #1 and explain how you would model it.
We modeled molecules of water by seeing what they do and how they react to certain materials. Then we created small models that showed what they did and how. We also made a dance that demonstrated how water molecules move and in what ways at what speed. These models can explain cohesion and adhesion because if you relate them you can really see what they related to adhesion and cohesion and you can see water molecules in action in a way that is much easier to understand. Well one model I want to talk about is one of the cohesion models. The one When we dropped pins into the different liquids to see which one was the strongest cohesion liquid and water won. What I would of done would be to try more than 3 different liquids and drop in different objects with different weights. This would show the strength in each liquid. I would also want to see if the amount of liquid matters so i would have the same liquid in different quantities.
Discuss one way in which either the cohesive or adhesive properties of water play an important role in the (choose depending on your group).
Cohesiveness plays an important role in the Geosphere because with out this, water in a large group would be able to find its way into the geosphere quickly. since it is in such a large group it would take a while for a lot of water to get in and even once it got in the high temperature it would be forced to evaporate.
What is polarity? What causes a molecule to be polar? Give an example.
Polarity is when there is an imbalanced amount of electric charge caused by the unequal "ELECTRON HUNGER" of different atoms in a molecule. What causes a molecule to be polar is when the amount of electric charge is imbalanced, like a water molecule. A water molecule has 2 positive spots and whole negative side which makes it imbalanced.
How do polar and non-polar molecules behave differently?
When they have some form of polarity to them, their poles are attracted to other polar molecules that are opposite so a positive pole can meet with a negative pole. A non polar molecule cant be attracted to anything because it has nothing.
