what is water
polar molecule, oxygen is negative, hydrogen is poisitive, when two water molecules come in contact the opposite charges repell and a hydrogen bond is formed called a cohesion bond
1 of 6
waters surface tension propeties
water has a high surface tension to to the cohesion between molecules, can support the bodies of aqauaic insects
2 of 6
waters solvent propeties
water is polar so it allows it to attract charge molecules such as ions. the chemsicals dissolve and form a transport meduim, non polar molcuels such as lipisds cant dissolve
3 of 6
waters specific heat propeties
has a high specific heat as lots of energy is required to raise the tempertaure of water, this makes the temp more stable for aqautic habitats
4 of 6
waters latent heat
has a high latent heat as at lot of energy is needed to change the liqued into a vapour state
5 of 6
other porpoeties of water
water is transparent so light can pass through photosynthesis the aquaticc plants
