properties of water | adhesion and cohesion | bonds | acids and bases | random |
---|---|---|---|---|
it freezes and forms ice
What does water do when it gets cold?
|
Water sticking together
What is cohesion?
|
a hydrogen bond
besides a polar covalent bond, what kind of other bond does water have
|
What is the highest and lowest ph on the scale
The lowest is 1 or very acidic and the highest is 14 or very basic
|
solid, liquid, gas
what are the 3 physical states of an element
|
it has to take in a lot of heat before it can be hot
What does it mean that water has the ability to moderate temperature?
|
water sticking to other substances
What is adhesion?
|
the positive and negative ions are distributed unevenly
what does having a polar bond mean?
|
the measure of acidity or alkalinity
What is ph
|
the attraction of atoms from the electrons
what is electronegativity
|
waters cohesion water sticks together because of the positive hydrogen and the negative oxygen
what does water cohesion do
|
The water molecules form hydrogen bonds with each other
How does cohesion work?
|
the electrons are shared within the compound
what does having a covalent bond mean
|
7 or neutral
what is the ph of water?
|
H2O
what is the chemical compound of water
|
it can dissolve a lot of things due to hydrogen bonding
What does it mean to have versatility as a solvent?
|
water is attracted to plants and more than it is to water to it forces the water to go up inside the plant
How does adhesion work?
|
polarity allows bonds between molecules
what does polarity do with bonds?
|
a substance that neutralizes alkaline substances
What is an acid
|
the measure of how hard it is to break the surface of the liquid
what is surface tension?
|
cohesive behavior, ability to moderate temperature, expansion upon freezing, versatility as a solvent
what are the 4 properties of water
|
cohesion causes water to stick to itself and adhesion causes water to stick to other things helping it climb through the human body or plants carrying other ​needed substances
How do adhesion and cohesion make life possible?
|
it means that the electrons are shared between molecules and all the ions inside of the compound are shared unevenly
what does having a polar covalent bond mean
|
a substance that can neutralize the acids
What is a base
|
liquid, water- solid, ice- gas water vapor
What are the 3 states water can be in and what are they called specifically for water
