Water & Its Characteristics
Water atoms when joined together look like mickey mouse!
It has all of the following....
- Adhesion- the attachment of one surface to the other.
- Cohesion- the attraction of one surface to another.
- Polarity- the physical alignment of atoms.
- Heat Storage- the trapping of thermal heat in an object
- pH- measure of acidity or basicity (anything 5 and above is considered basic)
Water Molecules
This image represents water and its molecule state. You can see that it looks like mickey mouse. You can also spot that the molecules are very far apart from each other because water is a "flowy" substance.
Adhesion
You can see how the water droplets stick to the leaves. This is adhesion up close.
pH Scale
This is an image of the pH table. It shows everything that is basic and acidic. It also shows the number 7 which is neither basic or acidic , just pure water.
Enzymes
What is an enzyme?
An enzyme is a catalyst, a catalyst is something that speeds the rate of a chemical reaction without changing itself, that increases the speed at which a chemical reaction happens.
- Most enzymes are proteins
