Emergent properties
|
when single things come together and form more complex behaviors collectively
|
|
|
Cohesion
|
Tendency of molecules to stick to each other
|
|
|
Adhesion
|
Tendency of molecules to stick to other substances
|
|
|
Surface Tension (Relating to water)
|
Results when the water molecules on the surface of the water are only attached to molecules below them in the actual water, thus having no H-Bonds with any molecules above them. Causing their surface to remain very strong
|
|
|
Specific Heat
|
amount of heat a substance needs to absorb in order to increase the temperature of 1g of substance by 1C.
|
|
|
Waters Specific Heat
|
1g per / 1 Degree C
|
|
|
High Heat Capacity
|
Substance can absorb more energy or more heat with a smaller change in temperature
|
|
|
High Heat of Evaporation
|
Regarding converting a substance from a liquid to a gas. Higher heat means its going to take more heat in order to make this change of state.

|
Explain why ice is less dense then liquid water
|
-Due to the way the hydrogen bonds are form when liquid is in a solid state, there is more distance between the individual molecules therefore causing the ice to be less dense and float.
|
|
|
Explain why ice being less dense then liquid water is essential to life on earth
|
-First, when a lake freezes if ice was more dense it would sink therefore causing the lake to freeze from the bottom up and eliminating life on the bottom to the top as it travels
-Second, when the top layer freezes it actually insulates the lower portion on the water not allowing it to freeze and maintaining life |
