Properties
This property of water allows a pin to float on the surface of water.
What is cohesion at the surface (surface tension)?
This is the number of hydrogen atoms in a water molecule.
What is two?
Define polar
one positive side and one negative side
True or false:ice sinks in water
false
This property of water demonstrates the attraction of one water molecule to another.
What is cohesion?
This is the property that describes water's ability to dissolve many substances.
What is universal solvent?
define surface tension
cohesion at the surface of water
True or false: everything can mix with water
False- nonpolar (hydrophobic) substances will not mix
This property of water allows water to "climb" up substances.
What is capillary action?
This property of water is the reason why we have relatively stable temperatures on earth.
define hydrogen bonds
the attraction between two molecules due to opposite charges
True or false: Soap breaks apart hydrogen bonds
True
Water molecules tend to "stick" together because of positively and negatively charged "ends" of the molecule. So, we say it is what kind of molecule?
What is a polar molecule?
This property of water is exemplified by water sticking to a car window while driving through the rain
What is adhesion?
What subatomic particle is responsible for atoms bonding together to form molecules
Electron
True or false: Water is polar because the hydrogen hogs the electrons
False- oxygen hogs the electrons
This is the name for the attraction of two different molecules toward each other, due to their opposite charges
What are hydrogen bonds?
List 5 properties of water and define what they each are
varys
Cohesion and adhesion working together to allow water to passively work against gravity
True or false: Water will dissolve all polar substances
True- only polar substances will dissolve, nonpolar will not
