WATER Flashcards
Define the term Dipole ?
A polar molecule with a positive and negative charge
Water molecule ?
The water molecule is a dipole meaning it has a positively charged end (hydrogen) and a negatively charged end (oxygen) .No overall charge
Properties of water ?
polar, high specific heat capacity, high latent heat of vaporization, solvent, expands upon freezing, slight tendency to ionize, high surface tension ,high density , transparency
Key property of water for organisms
The temperature of water tends to not change rapidly allowing for aquatic habitats to form
Water is held by ?
Covalent Bond
Cohesion of water ?
Where water molecules attract each other forming hydrogen bonds
Hydrogen bonds are ?
individually weak but collectively strong forming a lattice
Water is ..
Transparent allowing light to pass through to allow photosynthesis to take place
Water has a high
Surface tension due to its polarity
Water is a M
Metabolite . Involved in Chemical and physical processes
Water has a high surface tension
due to the ordered arrangement and cohesion of molecules at the surface
Why is water a good solvent
Due to its polarity and ability to form hydrogen bonds . It’s able to dissolve many different kinds of molecules
Water has an unbalanced
Distribution of electrons
Water is made from
2 hydrogen bonds and 1 oxygen atom. H20
water acts as a temp
-Temperature buffer
-organisms are able to maintain optimum enzyme activity
