Hydrogen Atom: each hydrogen atom has a slight positive charge
Oxygen Atom: The oxygen atom has a slight negative charge
Key Properties of Water
The properties of water include:
-High specific heat
What is the advantage of the interaction of water and fibers in clothing?
is the tightness across the surface of water that is caused by the polar molecules pulling on one another.
Solution: is a mixture that forms when one substance dissolves another.
Solvent: is the substance doing the dissolving.
is the amount of heat needed to increase the temperature of a certain mass of a substance by 1°C.
Water requires a lot of heat to increase its temperature due to the strong attraction among its molecules.
What effect does water’s high specific heat index have on land areas? How does it affect where you live?
The three states of water
What are some examples of Evaporation?
Adhesion: the ability of water to stick firmly to something not similar to it. (i.e. water to another substance)
Cohesion: the force of attraction by which the molecules of water, solid or liquid, tend to remain together. ( i.e. water to water)
