structure and properties of water

are the oxygen atoms in water positive or negative

oxygen atoms are slightly negative compared to the hydrogen atoms

what is the shape of a water molecule

v shaped

what do the slightly diffetn charges in water make the molecule

it makes it a dipole

what are the bonds between the individual molecules in water

hydrogen bonds

what is it called when an hydrogen molecule binds to itself

cohesion

what is it called when an hydrogen molecule binds to something else

adhesion

what will dissolve in water and how

good solvent for any solute which has a dipole. it dissolve through being surrounded by a 'shell' of water molecules

what are the hydrogen bonds like in ice

they are stable and in an open lattice

how dense is ice and why

less dense - the water molecules are further apart in the open lattice structure so ice is able to float

what are the hydrogen bonds like in liquid water

constantly breaking and reforming

what is the specific heat capacity and latent heat of vaporisation like in liquid water

high

where is surface tension located

it is the water and gas air interface

what is surface tension caused by

hydrogen bonds

what does ice being less dense than water mean

it forms an insulating layer over aquatic habitats whilst allowing the animals in water to be able to swim

what does water being liquid at most temps on earth mean

used as a medium for most chemical reactions and helps transport chemicals

what does water being transparent mean

light can pass through water to aquatic plants for photosynthesis

what does water having a high surface tension mean

it can support the mass of organisms such as pond skaters by adhesive forces. it also allows it to be pulled through plants

what does the high specific heat capcity of water mean

aquatic habitats and cytoplasm of cell remain a stable temperature

what does the high specific latent heat of vaporisation of water mean

it can act as a coolant and aquatic habitats dont evaporate easily

what does the high density of liquid water mean for aquatic animals

provides support and buoyancy

state the 7 proprieties of water

-high density
-high latent heat of vaporisation
-high specific heat capcity
-has cohesion
-is a transport medium
-is transparent
